[ Upstream commit 25bdbfbb2d8331a67824dd03d0087e9c98835f3a ]
The Saitek X65 joystick has a pair of axes that were used as mouse
pointer controls by the Windows driver. The corresponding usage page is
the Game Controls page, which is not recognized by the generic HID
driver, and therefore, both axes get mapped to ABS_MISC. The quirk makes
the second axis get mapped to ABS_MISC+1, and therefore made available
separately.

commit 1e0d4e6225996f05271de1ebcb1a7c9381af0b27 upstream.
get_device(shost->shost_gendev.parent) is called after host state has
switched to SHOST_RUNNING. scsi_host_dev_release() shouldn't release the
parent device if host state is still SHOST_CREATED.

commit 11714026c02d613c30a149c3f4c4a15047744529 upstream.
scsi_host_dev_release() only frees dev_name when host state is
SHOST_CREATED. After host state has changed to SHOST_RUNNING,
scsi_host_dev_release() no longer cleans up.
Fix this by doing a put_device(&shost->shost_dev) in the failure path when
host state is SHOST_RUNNING. Move get_device(&shost->shost_gendev) before
device_add(&shost->shost_dev) so that scsi_host_cls_release() can do a put
on this reference.

commit 3719f4ff047e20062b8314c23ec3cab84d74c908 upstream.
When scsi_add_host_with_dma() returns failure, the caller will call
scsi_host_put(shost) to release everything allocated for this host
instance. Consequently we can't also free allocated stuff in
scsi_add_host_with_dma(), otherwise we will end up with a double free.
Strictly speaking, host resource allocations should have been done in
scsi_host_alloc(). However, the allocations may need information which is
not yet provided by the driver when that function is called. So leave the
allocations where they are but rely on host device's release handler to
free resources.

commit 66a834d092930cf41d809c0e989b13cd6f9ca006 upstream.
After device is initialized via device_initialize(), or its name is set via
dev_set_name(), the device has to be freed via put_device(). Otherwise
device name will be leaked because it is allocated dynamically in
dev_set_name().
Fix the leak by replacing kfree() with put_device(). Since
scsi_host_dev_release() properly handles IDA and kthread removal, remove
special-casing these from the error handling as well.

commit 2ba0aa2feebda680ecfc3c552e867cf4d1b05a3a upstream.
The function init_cq_frag_buf() can be called to initialize the current CQ
fragments buffer cq->buf, or the temporary cq->resize_buf that is filled
during CQ resize operation.
However, the offending commit started to use function get_cqe() for
getting the CQEs, the issue with this change is that get_cqe() always
returns CQEs from cq->buf, which leads us to initialize the wrong buffer,
and in case of enlarging the CQ we try to access elements beyond the size
of the current cq->buf and eventually hit a kernel panic.

commit 404e5a12691fe797486475fe28cc0b80cb8bef2c upstream.
Currently when mlx4 maps the hca_core_clock page to the user space there
are read-modifiable registers, one of which is semaphore, on this page as
well as the clock counter. If user reads the wrong offset, it can modify
the semaphore and hang the device.
Do not map the hca_core_clock page to the user space unless the device has
been put in a backwards compatibility mode to support this feature.
After this patch, mlx4 core_clock won't be mapped to user space on the
majority of existing devices and the uverbs device time feature in
ibv_query_rt_values_ex() will be disabled.

commit 408434036958699a7f50ddec984f7ba33e11a8f5 upstream.
Update CP_PROTECT register programming based on downstream.
A6XX_PROTECT_RW is renamed to A6XX_PROTECT_NORDWR to make things aligned
and also be more clear about what it does.
Note that this required switching to use the CP_ALWAYS_ON_COUNTER as the
GMU counter is not accessible from the cmdstream. Which also means
using the CPU counter for the msm_gpu_submit_flush() tracepoint (as
catapult depends on being able to compare this to the start/end values
captured in cmdstream). This may need to be revisited when IFPC is
enabled.
Also, compared to downstream, this opens up CP_PERFCTR_CP_SEL as the
userspace performance tooling (fdperf and pps-producer) expect to be
able to configure the CP counters.

commit c8a570443943304cac2e4186dbce6989b6c2b8b5 upstream.
The calclulation of how many bytes we stuff into the
DSI pipeline for video mode panels is off by three
orders of magnitude because we did not account for the
fact that the DRM mode clock is in kilohertz rather
than hertz.
This used to be:
drm_mode_vrefresh(mode) * mode->htotal * mode->vtotal
which would become for example for s6e63m0:
60 x 514 x 831 = 25628040 Hz, but mode->clock is
25628 as it is in kHz.
This affects only the Samsung GT-I8190 "Golden" phone
right now since it is the only MCDE device with a video
mode display.
Curiously some specimen work with this code and wild
settings in the EOL and empty packets at the end of the
display, but I have noticed an eeire flicker until now.
Others were not so lucky and got black screens.

commit 8212937305f84ef73ea81036dafb80c557583d4b upstream.
Current sequence utilizes dwc3_gadget_disable_irq() alongside
synchronize_irq() to ensure that no further DWC3 events are generated.
However, the dwc3_gadget_disable_irq() API only disables device
specific events. Endpoint events can still be generated. Briefly
disable the interrupt line, so that the cleanup code can run to
prevent device and endpoint events. (i.e. __dwc3_gadget_stop() and
dwc3_stop_active_transfers() respectively)
Without doing so, it can lead to both the interrupt handler and the
pullup disable routine both writing to the GEVNTCOUNT register, which
will cause an incorrect count being read from future interrupts.

commit bc537e65b09a05923f98a31920d1ab170e648dba upstream.
Changing the BD71837 voltages for other regulators except the first 4 BUCKs
should be forbidden when the regulator is enabled. There may be out-of-spec
voltage spikes if the voltage of these "non DVS" bucks is changed when
enabled. This restriction was accidentally removed when the LDO voltage
change was allowed for BD71847. (It was not noticed that the BD71837
BUCK7 used same voltage setting function as LDOs).
Additionally this bug causes incorrect voltage monitoring register access.
The voltage change function accidentally used for bd71837 BUCK7 is
intended to only handle LDO voltage changes. A BD71847 LDO specific
voltage monitoring disabling code gets executed on BD71837 and register
offsets are wrongly calculated as regulator is assumed to be an LDO.
Prevent the BD71837 BUCK7 voltage change when BUCK7 is enabled by using
the correct voltage setting operation.

commit 6f55c5dd1118b3076d11d9cb17f5c5f4bc3a1162 upstream.
The MAX77620 driver fails to re-probe on deferred probe because driver
core tries to claim resources that are already claimed by the PINCTRL
device. Use device_set_of_node_from_dev() helper which marks OF node as
reused, skipping erroneous execution of pinctrl_bind_pins() for the PMIC
device on the re-probe.

commit 98e48cd9283dbac0e1445ee780889f10b3d1db6a upstream.
For the boot-on/always-on regulators the set_machine_constrainst() is
called before resolving rdev->supply. Thus the code would try to enable
rdev before enabling supplying regulator. Enforce resolving supply
regulator before enabling rdev.

commit 032e288097a553db5653af552dd8035cd2a0ba96 upstream.
usb_assign_descriptors() is called with 5 parameters,
the last 4 of which are the usb_descriptor_header for:
full-speed (USB1.1 - 12Mbps [including USB1.0 low-speed @ 1.5Mbps),
high-speed (USB2.0 - 480Mbps),
super-speed (USB3.0 - 5Gbps),
super-speed-plus (USB3.1 - 10Gbps).
The differences between full/high/super-speed descriptors are usually
substantial (due to changes in the maximum usb block size from 64 to 512
to 1024 bytes and other differences in the specs), while the difference
between 5 and 10Gbps descriptors may be as little as nothing
(in many cases the same tuning is simply good enough).
However if a gadget driver calls usb_assign_descriptors() with
a NULL descriptor for super-speed-plus and is then used on a max 10gbps
configuration, the kernel will crash with a null pointer dereference,
when a 10gbps capable device port + cable + host port combination shows up.
(This wouldn't happen if the gadget max-speed was set to 5gbps, but
it of course defaults to the maximum, and there's no real reason to
artificially limit it)
The fix is to simply use the 5gbps descriptor as the 10gbps descriptor,
if a 10gbps descriptor wasn't provided.
Obviously this won't fix the problem if the 5gbps descriptor is also
NULL, but such cases can't be so trivially solved (and any such gadgets
are unlikely to be used with USB3 ports any way).

commit 6fc1db5e6211e30fbb1cee8d7925d79d4ed2ae14 upstream.
During unbind, ffs_func_eps_disable() will be executed, resulting in
completion callbacks for any pending USB requests. When using AIO,
irrespective of the completion status, io_data work is queued to
io_completion_wq to evaluate and handle the completed requests. Since
work runs asynchronously to the unbind() routine, there can be a
scenario where the work runs after the USB gadget has been fully
removed, resulting in accessing of a resource which has been already
freed. (i.e. usb_ep_free_request() accessing the USB ep structure)
Explicitly drain the io_completion_wq, instead of relying on the
destroy_workqueue() (in ffs_data_put()) to make sure no pending
completion work items are running.

commit f247f0a82a4f8c3bfed178d8fd9e069d1424ee4e upstream.
If ucsi_init() fails for some reason (e.g. ucsi_register_port()
fails or general communication failure to the PPM), particularly at
any point after the GET_CAPABILITY command had been issued, this
results in unwinding the initialization and returning an error.
However the ucsi structure's ucsi_capability member retains its
current value, including likely a non-zero num_connectors.
And because ucsi_init() itself is done in a workqueue a UCSI
interface driver will be unaware that it failed and may think the
ucsi_register() call was completely successful. Later, if
ucsi_unregister() is called, due to this stale ucsi->cap value it
would try to access the items in the ucsi->connector array which
might not be in a proper state or not even allocated at all and
results in NULL or invalid pointer dereference.
Fix this by clearing the ucsi->cap value to 0 during the error
path of ucsi_init() in order to prevent a later ucsi_unregister()
from entering the connector cleanup loop.

Reverting this commit brings back a properly functioning ECM
Gadget. An analysis of the commit seems to indicate that a mistake was
made: the previous code was not falling through into the
MUSB_QUIRK_B_INVALID_VBUS_91, but now it is, unless the condition is
taken.
Changing the logic to be as it was before the problematic commit *and*
only conditionally scheduling musb->irq_work resolves the regression:

commit d00889080ab60051627dab1d85831cd9db750e2a upstream.
There is no validation of the index from dwc3_wIndex_to_dep() and we might
be referring a non-existing ep and trigger a NULL pointer exception. In
certain configurations we might use fewer eps and the index might wrongly
indicate a larger ep index than existing.
By adding this validation from the patch we can actually report a wrong
index back to the caller.
In our usecase we are using a composite device on an older kernel, but
upstream might use this fix also. Unfortunately, I cannot describe the
hardware for others to reproduce the issue as it is a proprietary
implementation.

commit 03715ea2e3dbbc56947137ce3b4ac18a726b2f87 upstream.
There exists a possible scenario in which dwc3_gadget_init() can fail:
during during host -> peripheral mode switch in dwc3_set_mode(), and
a pending gadget driver fails to bind. Then, if the DRD undergoes
another mode switch from peripheral->host the resulting
dwc3_gadget_exit() will attempt to reference an invalid and dangling
dwc->gadget pointer as well as call dma_free_coherent() on unmapped
DMA pointers.
The exact scenario can be reproduced as follows:
- Start DWC3 in peripheral mode
- Configure ConfigFS gadget with FunctionFS instance (or use g_ffs)
- Run FunctionFS userspace application (open EPs, write descriptors, etc)
- Bind gadget driver to DWC3's UDC
- Switch DWC3 to host mode
=> dwc3_gadget_exit() is called. usb_del_gadget() will put the
ConfigFS driver instance on the gadget_driver_pending_list
- Stop FunctionFS application (closes the ep files)
- Switch DWC3 to peripheral mode
=> dwc3_gadget_init() fails as usb_add_gadget() calls
check_pending_gadget_drivers() and attempts to rebind the UDC
to the ConfigFS gadget but fails with -19 (-ENODEV) because the
FFS instance is not in FFS_ACTIVE state (u |
