[ Upstream commit 27c3943683f74e35e1d390ceb2e3639eff616ad6 ]
mtk_vcodec_release_dec_pm() will be called in two places:
a. mtk_vcodec_init_dec_pm() succeed while mtk_vcodec_probe() return error.
b. mtk_vcodec_dec_remove().
In both cases put_device() call is needed, since of_find_device_by_node()
was called in mtk_vcodec_init_dec_pm() previously.
Thus add put_devices() call in mtk_vcodec_release_dec_pm()

[ Upstream commit a08ad6339e0441ca12533969ed94a87e3655426e ]
The are two instances of sizeof() being used incorrectly. The
sizeof(void *) is incorrect because urb_buffer is a char ** pointer,
fix this by using sizeof(*dev->urb_buffer). The sizeof(dma_addr_t *)
is incorrect, it should be sizeof(*dev->urb_dma), which is a dma_addr_t
and not a dma_addr_t *. This errors did not cause any issues because
it just so happens the sizes are the same.

gasket_interrupt_set_eventfd() misses to call eventfd_ctx_put() in an

[ Upstream commit 3952659a6108f77a0d062d8e8487bdbdaf52a66c ]
gb_pm_runtime_get_sync has increased the usage counter of the device here.
Forgetting to call gb_pm_runtime_put_noidle will result in usage counter
leak in the error branch of (gbcodec_hw_params and gbcodec_prepare). We

[ Upstream commit 3b5c130fb2e4c045369791c33c83b59f6e84f7d6 ]
The return value of qat_hal_rd_ae_csr() is always a CSR value and never
a status and should not be stored in the status variable of
qat_hal_put_rel_rd_xfer().
This removes the assignment as qat_hal_rd_ae_csr() is not expected to
fail.
A more comprehensive handling of the theoretical corner case which could
result in a fail will be submitted in a separate patch.

[ Upstream commit fbb7dc5db6dee553b5a07c27e86364a5223e244c ]
gcc points out a suspicious mixing of enum types in a function that
converts from MTHCA_OPCODE_* values to IB_WC_* values:
drivers/infiniband/hw/mthca/mthca_cq.c: In function 'mthca_poll_one':
drivers/infiniband/hw/mthca/mthca_cq.c:607:21: warning: implicit conversion from 'enum <anonymous>' to 'enum ib_wc_opcode' [-Wenum-conversion]
607 | entry->opcode = MTHCA_OPCODE_INVALID;
Nothing seems to ever check for MTHCA_OPCODE_INVALID again, no idea if
this is meaningful, but it seems harmless as it deals with an invalid
input.
Remove MTHCA_OPCODE_INVALID and set the ib_wc_opcode to 0xFF, which is
still bogus, but at least doesn't make compiler warnings.

[ Upstream commit 4b6ea87be44ef34732846fc71e44c41125f0c4fa ]
On geni-i2c transfers using DMA, it was seen that if you program the
command (I2C_READ) before calling geni_se_rx_dma_prep() that it could
cause interrupts to fire. If we get unlucky, these interrupts can
just keep firing (and not be handled) blocking further progress and
hanging the system.
In commit 02b9aec59243 ("i2c: i2c-qcom-geni: Fix DMA transfer race")
we avoided that by making sure we didn't program the command until
after geni_se_rx_dma_prep() was called. While that avoided the
problems, it also turns out to be invalid. At least in the TX case we
started seeing sporadic corrupted transfers. This is easily seen by
adding an msleep() between the DMA prep and the writing of the
command, which makes the problem worse. That means we need to revert
that commit and find another way to fix the bogus IRQs.
Specifically, after reverting commit 02b9aec59243 ("i2c:
i2c-qcom-geni: Fix DMA transfer race"), I put some traces in. I found
that the when the interrupts were firing like crazy:
- "m_stat" had bits for M_RX_IRQ_EN, M_RX_FIFO_WATERMARK_EN set.
- "dma" was set.
Further debugging showed that I could make the problem happen more
reliably by adding an "msleep(1)" any time after geni_se_setup_m_cmd()
ran up until geni_se_rx_dma_prep() programmed the length.
A rather simple fix is to change geni_se_select_dma_mode() so it's a
true inverse of geni_se_select_fifo_mode() and disables all the FIFO
related interrupts. Now the problematic interrupts can't fire and we
can program things in the correct order without worrying.
As part of this, let's also change the writel_relaxed() in the prepare
function to a writel() so that our DMA is guaranteed to be prepared
now that we can't rely on geni_se_setup_m_cmd()'s writel().
NOTE: the only current user of GENI_SE_DMA in mainline is i2c.

commit 2f70e49ed860020f5abae4f7015018ebc10e1f0e upstream.
At the moment opening a serial device node (such as /dev/ttyS3)
succeeds even if there is no actual serial device behind it.
Reading/writing/ioctls fail as expected because the uart port is not
initialized (the type is PORT_UNKNOWN) and the TTY_IO_ERROR error state
bit is set fot the tty.
However setting line discipline does not have these checks
8250_port.c (8250 is the default choice made by univ8250_console_init()).
As the result of PORT_UNKNOWN, uart_port::iobase is NULL which
a platform translates onto some address accessing which produces a crash
like below.
This adds tty_port_initialized() to uart_set_ldisc() to prevent the crash.

commit 381d34e376e3d9d27730fda8a0e870600e6c8196 upstream.
It sounds unwise to let user space pass an unchecked 32-bit offset into a
kernel structure in an ioctl. This is an unsigned variable, so checking the
upper bound for the size of the structure it points into is sufficient to
avoid data corruption, but as the pointer might also be unaligned, it has
to be written carefully as well.
While I stumbled over this problem by reading the code, I did not continue
checking the function for further problems like it.

commit a353397b0d5dfa3c99b372505db3378fc919c6c6 upstream.
In many cases a function that supports SuperSpeed can very well
operate in SuperSpeedPlus, if a gadget controller supports it,
as the endpoint descriptors (and companion descriptors) are
generally identical and can be re-used. This is true for two
commonly used functions: Android's ADB and MTP. So we can simply
assign the usb_function's ssp_descriptors array to point to its
ss_descriptors, if available. Similarly, we need to allow an
epfile's ioctl for FUNCTIONFS_ENDPOINT_DESC to correctly
return the corresponding SuperSpeed endpoint descriptor in case
the connected speed is SuperSpeedPlus as well.
The only exception is if a function wants to implement an
Isochronous endpoint capable of transferring more than 48KB per
service interval when operating at greater than USB 3.1 Gen1
speed, in which case it would require an additional SuperSpeedPlus
Isochronous Endpoint Companion descriptor to be returned as part
of the Configuration Descriptor. Support for that would need
to be separately added to the userspace-facing FunctionFS API
which may not be a trivial task--likely a new descriptor format
(v3?) may need to be devised to allow for separate SS and SSP
descriptors to be supplied.

a rework of the dm table code which changed the calling context.
Issuing a BUG for a wrong calling context is frowned upon and
in_interrupt() is deprecated and only covering parts of the wrong
contexts. The sanity check for the context is covered by
CONFIG_DEBUG_ATOMIC_SLEEP and other debug facilities already.

[ Upstream commit 0a35dc41fea67ac4495ce7584406bf9557a6e7d0 ]
It was observed that sending data via batadv over vxlan (on top of
wireguard) reduced the performance massively compared to raw ethernet or
batadv on raw ethernet. A check of perf data showed that the
vxlan_build_skb was calling all the time pskb_expand_head to allocate
enough headroom for:
min_headroom = LL_RESERVED_SPACE(dst->dev) + dst->header_len
+ VXLAN_HLEN + iphdr_len;
But the vxlan_config_apply only requested needed headroom for:
lowerdev->hard_header_len + VXLAN6_HEADROOM or VXLAN_HEADROOM
So it completely ignored the needed_headroom of the lower device. The first
caller of net_dev_xmit could therefore never make sure that enough headroom
was allocated for the rest of the transmit path.
