commit 25a1433216489de4abc889910f744e952cb6dbae upstream.
There are two bugs:
1) If ida_simple_get() fails then this code calls put_device(carrier)
but we haven't yet called get_device(carrier) and probably that
leads to a use after free.
2) After device_initialize() then we need to use put_device() to
release the bus. This will free the internal resources tied to the
device and call mcb_free_bus() which will free the rest.
Fixes: 5d9e2ab9fea4 ("mcb: Implement bus->dev.release callback")
Fixes: 18d288198099 ("mcb: Correctly initialize the bus's device")

commit 58877b0824da15698bd85a0a9dbfa8c354e6ecb7 upstream.
It has been observed with certain PCIe USB cards (like Inateck connected
to AM64 EVM or J7200 EVM) that as soon as the primary roothub is
registered, port status change is handled even before xHC is running
leading to cold plug USB devices not detected. For such cases, registering
both the root hubs along with the second HCD is required. Add support for
deferring roothub registration in usb_add_hcd(), so that both primary and
secondary roothubs are registered along with the second HCD.

commit 8cfac9a6744fcb143cb3e94ce002f09fd17fadbb upstream.
After we start to do core soft reset while usb role switch,
the phy init is invoked at every switch to device mode, but
its counter part de-init is missing, this causes the actual
phy init can not be done when we really want to re-init phy
like system resume, because the counter maintained by phy
core is not 0. considering phy init is actually redundant for
role switch, so move out the phy init from core soft reset to
dwc3 core init where is the only place required.

commit 5fdb55c1ac9585eb23bb2541d5819224429e103d upstream.
During BC_FREE_BUFFER processing, the BINDER_TYPE_FDA object
cleanup may close 1 or more fds. The close operations are
completed using the task work mechanism -- which means the thread
needs to return to userspace or the file object may never be
dereferenced -- which can lead to hung processes.
Force the binder thread back to userspace if an fd is closed during
BC_FREE_BUFFER handling.

commit d91adc5322ab53df4b6d1989242bfb6c63163eb2 upstream.
This reverts commit f3de5d857bb2362b00e2a8d4bc886cd49dcb66db.
That commit broke USB on all routers that have USB always powered on and
don't require toggling any GPIO. It's a majority of devices actually.
The original code worked and seemed safe: vcc GPIO is optional and
bcma_hci_platform_power_gpio() takes care of checking the pointer before
using it.
This revert fixes:

commit 91fac0741d4817945c6ee0a17591421e7f5ecb86 upstream.
If the driver runs out of minor numbers it would release minor 0 and
allow another device to claim the minor while still in use.
Fortunately, registering the tty class device of the second device would
fail (with a stack dump) due to the sysfs name collision so no memory is
leaked.

commit 91bb163e1e4f88092f50dfaa5a816b658753e4b2 upstream.
According USB spec each ISOC transaction should be performed in a
designated for that transaction interval. On bus errors or delays
in operating system scheduling of client software can result in no
packet being transferred for a (micro)frame. An error indication
should be returned as status to the client software in such a case.
Current implementation in case of missed/dropped interval send same
data in next possible interval instead of reporting missed isoc.
This fix complete requests with -ENODATA if interval elapsed.
HSOTG core in BDMA and Slave modes haven't HW support for
(micro)frames tracking, this is why SW should care about tracking
of (micro)frames. Because of that method and consider operating
system scheduling delays, added few additional checking's of elapsed
target (micro)frame:
1. Immediately before enabling EP to start transfer.
2. With any transfer completion interrupt.
3. With incomplete isoc in/out interrupt.
4. With EP disabled interrupt because of incomplete transfer.
5. With OUT token received while EP disabled interrupt (for OUT
transfers).
6. With NAK replied to IN token interrupt (for IN transfers).
As part of ISOC flow, additionally fixed 'current' and 'target' frame
calculation functions. In HS mode SOF limits provided by DSTS register
is 0x3fff, but in non HS mode this limit is 0x7ff.
Tested by internal tool which also using for dwc3 testing.

commit 17956b53ebff6a490baf580a836cbd3eae94892b upstream.
This loop is supposed to loop until if reads something other than
CS_IDST or until it times out after 30,000 attempts. But because of
the || vs && bug, it will never time out and instead it will loop a
minimum of 30,000 times.
This bug is quite old but the code is only used in USB_DEVICE_TEST_MODE
so it probably doesn't affect regular usage.

commit 2b58db229eb617d97d5746113b77045f1f884bcb upstream.
Measurements in different conditions showed that aardvark hardware PIO
response can take up to 1.44s. Increase wait timeout from 1ms to 1.5s to
ensure that we do not miss responses from hardware. After 1.44s hardware
returns errors (e.g. Completer abort).
The previous two patches fixed checking for PIO status, so now we can use
it to also catch errors which are reported by hardware after 1.44s.
After applying this patch, kernel can detect and print PIO errors to dmesg:

[ Upstream commit c3811a50addd23b9bb5a36278609ee1638debcf6 ]
Currently, iommu_init_ga() checks and disables IOMMU VAPIC support
(i.e. AMD AVIC support in IOMMU) when GAMSup feature bit is not set.
However it forgets to clear IRQ_POSTING_CAP from the previously set
amd_iommu_irq_ops.capability.
This triggers an invalid page fault bug during guest VM warm reboot
if AVIC is enabled since the irq_remapping_cap(IRQ_POSTING_CAP) is
incorrectly set, and crash the system with the following kernel trace.

switching the PCIE clock dynamically at runtime can lead to HDMI/DP

For SMU7-based asics, disable PCIE clock switching to avoid the issue.
AMD provide a parameter to disable PICE_DPM.

commit 020162d6f49f2963062229814a56a89c86cbeaa8 upstream.
This fixes a race condition: After pwmchip_add() is called there might
already be a consumer and then modifying the hardware behind the
consumer's back is bad. So reset before calling pwmchip_add().
Note that reseting the hardware isn't the right thing to do if the PWM
is already running as it might e.g. disable (or even enable) a backlight
that is supposed to be on (or off).

(Side-note: I don't know what this register setting actually does, if
this modifies the polarity there is an inconsistency because the
inversed polarity isn't considered if the PWM is already running during
.probe().)

commit 4a9344cd0aa4499beb3772bbecb40bb78888c0e1 upstream.
There are variables(power.may_skip_resume and dev->power.must_resume)
and DPM_FLAG_MAY_SKIP_RESUME flags to control the resume of devices after
a system wide suspend transition.
Setting the DPM_FLAG_MAY_SKIP_RESUME flag means that the driver allows
its "noirq" and "early" resume callbacks to be skipped if the device
can be left in suspend after a system-wide transition into the working
state. PM core determines that the driver's "noirq" and "early" resume
callbacks should be skipped or not with dev_pm_skip_resume() function by
checking power.may_skip_resume variable.
power.must_resume variable is getting set to false in __device_suspend()
function without checking device's DPM_FLAG_MAY_SKIP_RESUME settings.
In problematic scenario, where all the devices in the suspend_late
stage are successful and some device can fail to suspend in
suspend_noirq phase. So some devices successfully suspended in suspend_late
stage are not getting chance to execute __device_suspend_noirq()
to set dev->power.must_resume variable to true and not getting
resumed in early_resume phase.
Add a check for device's DPM_FLAG_MAY_SKIP_RESUME flag before
setting power.must_resume variable in __device_suspend function.

commit 3a2b2eb55681158d3e3ef464fbf47574cf0c517c upstream.
The Linux console's VT102 implementation already consumes OSC
("Operating System Command") sequences, probably because that's how
palette changes are transmitted.
In addition to OSC, there are three other major clases of ANSI control
strings: APC ("Application Program Command"), PM ("Privacy Message"),
and DCS ("Device Control String"). They are handled similarly to OSC in
terms of termination.
Source: vt100.net
Add three new enumerated states, one for each of these types. All three
are handled the same way right now--they simply consume input until
terminated. I hope to expand upon this firmament in the future. Add
new predicate ansi_control_string(), returning true for any of these
states. Replace explicit checks against ESosc with calls to this
function. Transition to these states appropriately from the escape
initiation (ESesc) state.
This was motivated by the following Notcurses bugs:
https://github.com/dankamongmen/notcurses/issues/2050
https://github.com/dankamongmen/notcurses/issues/1828
https://github.com/dankamongmen/notcurses/issues/2069
where standard VT sequences are not consumed by the Linux console. It's
not necessary that the Linux console *support* these sequences, but it
ought *consume* these well-specified classes of sequences.
Tested by sending a variety of escape sequences to the console, and
verifying that they still worked, or were now properly consumed.
Verified that the escapes were properly terminated at a generic level.
Verified that the Notcurses tools continued to show expected output on
the Linux console, except now without escape bleedthrough.

After d12e1c464988 ("net: dsa: b53: Set correct number of ports in the

which created an off by one error between the statically allocated

dsa_is_cpu_port() is used, we end-up accessing an out of bounds member
and causing a NPD.
