Merge tag 'media/v6.1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media

Pull missed media updates from Mauro Carvalho Chehab:
 "It seems I screwed-up my previous pull request: it ends up that only
  half of the media patches that were in linux-next got merged in -rc1.

  The script which creates the signed tags silently failed due to
  5.19->6.0 so it ended generating a tag with incomplete stuff.

  So here are the missing parts:

   - a DVB core security fix

   - lots of fixes and cleanups for atomisp staging driver

   - old drivers that are VB1 are being moved to staging to be
     deprecated

   - several driver updates - mostly for embedded systems, but there are
     also some things addressing issues with some PC webcams, in the UVC
     video driver"

d3dcbe24a0 USB/Thunderbolt changes for 6.1-rc1
Here is the big set of USB and Thunderbolt driver changes for 6.1-rc1.
 
 Nothing major in here, lots of little things with new devices supported
 and updates for a few drivers.  Highlights include:
 	- thunderbolt/USB4 devices supported a bit better than before,
 	  and some new ids to enable new hardware devices
 	- USB gadget uvc updates for newer video formats and better v4l
 	  integration (the v4l portions were acked by those maintainers)
 	- typec updates for tiny issues and more typec drivers for new
 	  chips.
 	- xhci tiny updates for minor issues
 	- big usb-serial ftdi_sio driver update to handle new devices
 	  better
 	- lots of tiny dwc3 fixes and updates for the IP block that is
 	  showing up everywhere these days
 	- dts updates for new devices being supported
 	- other tiny janitorial and cleanups fixes for lots of different
 	  USB drivers.  Full details are in the shortlog.
 
 All of these have been in linux-next for a while with no reported
 issues.

Commit d725d20e81 ("media: flexcop-usb: sanity checking of endpoint
type") tried to add an endpoint type sanity check for the single
isochronous endpoint but instead broke the driver by checking the wrong
descriptor or random data beyond the last endpoint descriptor.

Make sure to check the right endpoint descriptor.

150f7b11cb media: uvcvideo: Fix InterfaceProtocol for Quanta camera
The Quanta 0408:4034 camera implements UVC 1.5, and thus sets
bInterfaceProtocol to UVC_PC_PROTOCOL_15. Commit 95f03d9734 ("media:
uvcvideo: Limit power line control for Quanta cameras") added a quirk
for the device that incorrectly specified the UVC 1.0 protocol,
rendering the quirk inoperative. Fix it.

The commit ca9dc8d06a ("media: airspy: respect the DMA coherency

buf in the error handling code, missing deallocation in the success
path.

Fix this by freeing buf in the success path since this variable does not
have any references in other code.

ed5c2f5fd1 i2c: Make remove callback return void
The value returned by an i2c driver's remove function is mostly ignored.
(Only an error message is printed if the value is non-zero that the
error is ignored.)

So change the prototype of the remove function to return no value. This
way driver authors are not tempted to assume that passing an error to
the upper layer is a good idea. All drivers are adapted accordingly.
There is no intended change of behaviour, all callbacks were prepared to
return 0 before.

359c27c6dd media: hdpvr: fix error value returns in hdpvr_read
Error return values are supposed to be negative in hdpvr_read. Most
error returns are currently handled via an unsigned integer "ret". When
setting a negative error value to "ret", the value actually becomes a
large positive value, because "ret" is unsigned. Later on, the "ret"
value is returned. But as ssize_t is a 64-bit signed number, the error
return value stays a large positive integer instead of a negative
integer. This can cause an error value to be interpreted as the read
size, which can cause a buffer overread for applications relying on the
returned size.

945a9a8e44 media: pvrusb2: fix memory leak in pvr_probe
The error handling code in pvr2_hdw_create forgets to unregister the
v4l2 device. When pvr2_hdw_create returns back to pvr2_context_create,
it calls pvr2_context_destroy to destroy context, but mp->hdw is NULL,
which leads to that pvr2_hdw_destroy directly returns.

Fix this by adding v4l2_device_unregister to decrease the refcount of
usb interface.
