Also use KBUILD_MODNAME for module name.

This driver is only used by RALINK MIPS MT7621 SoCs. Tested by building
against that target using OpenWrt with Linux 5.10.10.

a274661d58 media: imx7: csi: Fix regression for parallel cameras on i.MX6UL
[ Upstream commit 9bac67214f ]

Commit 86e02d0787 ("media: imx5/6/7: csi: Mark a bound video mux as
a CSI mux") made an incorrect assumption that for imx7-media-csi,
the bound subdev must always be a CSI mux. On i.MX6UL/i.MX6ULL there
is no CSI mux at all, so do not return an error when the entity is not a
video mux and assign the IMX_MEDIA_GRP_ID_CSI_MUX group id only when
appropriate.

This is the same approach as done in imx-media-csi.c and it fixes the
csi probe regression on i.MX6UL.

Tested on a imx6ull-evk board.

40d53d436a media: imx: Fix csc/scaler unregister
[ Upstream commit 89b14485ca ]

The csc/scaler device private struct is released by
ipu_csc_scaler_video_device_release(), which can be called
by video_unregister_device() if there are no users
of the underlying struct video device.

Therefore, the mutex can't be held when calling
video_unregister_device() as its memory may be freed
by it, leading to a kernel oops.

Fortunately, the fix is quite simple as no locking
is needed when calling video_unregister_device(): v4l2-core
already has its own internal locking, and the structures
are also properly refcounted.

fe2e6f9342 media: imx: Unregister csc/scaler only if registered
[ Upstream commit bb2216548a ]

The csc/scaler device pointer (imxmd->m2m_vdev) is assigned
after the imx media device v4l2-async probe completes,
therefore we need to check if the device is non-NULL
before trying to unregister it.

This can be the case if the non-completed imx media device
is unbinded (or the driver is removed), leading to a kernel oops.

The "channel" is added to the "dev->channels" but then if

list so it could lead to a use after free.  Let's not add it to the

6709f280e7 staging: wfx: fix possible panic with re-queued frames
[ Upstream commit 26df933d9b ]

When the firmware rejects a frame (because station become asleep or
disconnected), the frame is re-queued in mac80211. However, the
re-queued frame was 8 bytes longer than the original one (the size of
the ICV for the encryption). So, when mac80211 try to send this frame
again, it is a little bigger than expected.
If the frame is re-queued secveral time it end with a skb_over_panic
because the skb buffer is not large enough.

Note it only happens when device acts as an AP and encryption is
enabled.

This patch more or less reverts the commit 049fde1304 ("staging: wfx:
drop useless field from struct wfx_tx_priv").

[ Upstream commit 61834c967a ]

The custom regulatory ruleset in the rtl8723bs driver lists an incorrect
number of rules: one too many. This results in an out-of-bounds access,
as detected by KASAN. This was possible thanks to the newly added support
for KASAN on ARMv7.

Fix this by filling in the correct number of rules given.

commit 73bc0b0c2a upstream.

During H264 API overhaul subtle bug was introduced Cedrus driver.
Progressive references have both, top and bottom reference flags set.
Cedrus reference list expects only bottom reference flag and only when
interlaced frames are decoded. However, due to a bug in Cedrus check,
exclusivity is not tested and that flag is set also for progressive
references. That causes "jumpy" background with many videos.

Fix that by checking that only bottom reference flag is set in control
and nothing else.

e885d1c515 staging: comedi: mf6x4: Fix AI end-of-conversion detection
commit 56c90457eb upstream.

I have had reports from two different people that attempts to read the
analog input channels of the MF624 board fail with an `ETIMEDOUT` error.

After triggering the conversion, the code calls `comedi_timeout()` with
`mf6x4_ai_eoc()` as the callback function to check if the conversion is
complete.  The callback returns 0 if complete or `-EBUSY` if not yet
complete.  `comedi_timeout()` returns `-ETIMEDOUT` if it has not
completed within a timeout period which is propagated as an error to the
user application.

The existing code considers the conversion to be complete when the EOLC
bit is high.  However, according to the user manuals for the MF624 and
MF634 boards, this test is incorrect because EOLC is an active low
signal that goes high when the conversion is triggered, and goes low
when the conversion is complete.  Fix the problem by inverting the test
of the EOLC bit state.

06ea594051 staging: ralink-gdma: fix kconfig dependency bug for DMA_RALINK
When DMA_RALINK is enabled and DMADEVICES is disabled, it results in the
following Kbuild warnings:

WARNING: unmet direct dependencies detected for DMA_ENGINE
  Depends on [n]: DMADEVICES [=n]
  Selected by [y]:
  - DMA_RALINK [=y] && STAGING [=y] && RALINK [=y] && !SOC_RT288X [=n]

WARNING: unmet direct dependencies detected for DMA_VIRTUAL_CHANNELS
  Depends on [n]: DMADEVICES [=n]
  Selected by [y]:
  - DMA_RALINK [=y] && STAGING [=y] && RALINK [=y] && !SOC_RT288X [=n]

The reason is that DMA_RALINK selects DMA_ENGINE and DMA_VIRTUAL_CHANNELS
without depending on or selecting DMADEVICES while DMA_ENGINE and
DMA_VIRTUAL_CHANNELS are subordinate to DMADEVICES. This can also fail
building the kernel as demonstrated in a bug report.

Honor the kconfig dependency to remove unmet direct dependency warnings
and avoid any potential build failures.

mt7621-pci 1e140000.pcie: Error requesting resources
mt7621-pci: probe of 1e140000.pcie failed with error -16
...

With commit 669cbc7081 ("PCI: Move DT resource setup into
devm_pci_alloc_host_bridge()"), the DT 'ranges' is parsed and populated
into resources when the host bridge is allocated. The resources are
requested as well, but that happens a 2nd time for this driver in
mt7621_pcie_request_resources(). Hence we should avoid this second
request.

Also, the bus ranges was also populated by default, so we can remove
it from mt7621_pcie_request_resources() to avoid the following trace
if we don't avoid it:

pci_bus 0000:00: busn_res: can not insert [bus 00-ff]
under domain [bus 00-ff] (conflicts with (null) [bus 00-ff])

Function 'mt7621_pcie_request_resources' has been renamed into
'mt7621_pcie_add_resources' which now is a more accurate name
for this function.

647a6002cb staging: comedi: cb_pcidas: Allow 2-channel commands for AO subdevice
The "cb_pcidas" driver supports asynchronous commands on the analog
output (AO) subdevice for those boards that have an AO FIFO.  The code
(in `cb_pcidas_ao_check_chanlist()` and `cb_pcidas_ao_cmd()`) to
validate and set up the command supports output to a single channel or
to two channels simultaneously (the boards have two AO channels).
However, the code in `cb_pcidas_auto_attach()` that initializes the
subdevices neglects to initialize the AO subdevice's `len_chanlist`
member, leaving it set to 0, but the Comedi core will "correct" it to 1
if the driver neglected to set it.  This limits commands to use a single
channel (either channel 0 or 1), but the limit should be two channels.
Set the AO subdevice's `len_chanlist` member to be the same value as the
`n_chan` member, which will be 2.

c6dbef7307 USB/PHY/Thunderbolt driver patches for 5.10-rc1
Here is the big set of USB, PHY, and Thunderbolt driver updates for
 5.10-rc1.
 
 Lots of tiny different things for these subsystems are in here,
 including:
 	- phy driver updates
 	- thunderbolt / USB 4 updates and additions
 	- USB gadget driver updates
 	- xhci fixes and updates
 	- typec driver additions and updates
 	- api conversions to various drivers for core kernel api changes
 	- new USB control message functions to make it harder to get
 	  wrong, as found by syzbot (took 2 tries to get it right)
 	- lots of tiny USB driver fixes and updates all over the place
 
 All of these have been in linux-next for a while, with the exception of
 the last "obviously correct" patch that updated a FALLTHROUGH comment
 that got merged last weekend.
