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"

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.

9958d30f38 media: Kconfig: cleanup VIDEO_DEV dependencies
media Kconfig has two entries associated to V4L API:
VIDEO_DEV and VIDEO_V4L2.

On Kernel 2.6.x, there were two V4L APIs, each one with its own flag.
VIDEO_DEV were meant to:
	1) enable Video4Linux and make its Kconfig options to appear;
	2) it makes the Kernel build the V4L core.

while VIDEO_V4L2 where used to distinguish between drivers that
implement the newer API and drivers that implemented the former one.

With time, such meaning changed, specially after the removal of
all V4L version 1 drivers.

At the current implementation, VIDEO_DEV only does (1): it enables
the media options related to V4L, that now has:

	menu "Video4Linux options"
		visible if VIDEO_DEV

	source "drivers/media/v4l2-core/Kconfig"
	endmenu

but it doesn't affect anymore the V4L core drivers.

The rationale is that the V4L2 core has a "soft" dependency
at the I2C bus, and now requires to select a number of other
Kconfig options:

	config VIDEO_V4L2
		tristate
		depends on (I2C || I2C=n) && VIDEO_DEV
		select RATIONAL
		select VIDEOBUF2_V4L2 if VIDEOBUF2_CORE
		default (I2C || I2C=n) && VIDEO_DEV

In the past, merging them would be tricky, but it seems that it is now
possible to merge those symbols, in order to simplify V4L dependencies.

Let's keep VIDEO_DEV, as this one is used on some make *defconfig
configurations.

8dbdcc7269 media: dib8000: Fix a memleak in dib8000_init()
In dib8000_init(), the variable fe is not freed or passed out on the
failure of dib8000_identify(&state->i2c), which could lead to a memleak.

Fix this bug by adding a kfree of fe in the error path.

This bug was found by a static analyzer. The analysis employs
differential checking to identify inconsistent security operations
(e.g., checks or kfrees) between two code paths and confirms that the
inconsistent operations are not recovered in the current function or
the callers, so they constitute bugs.

Note that, as a bug found by static analysis, it can be a false
positive or hard to trigger. Multiple researchers have cross-reviewed
the bug.

Builds with CONFIG_DVB_DIB8000=m show no new warnings,
and our static analyzer no longer warns about this code.

51c2664ab0 media: media si2168: fully initialize si2168 on resume only when necessary
At connection time (or boot) in si2168_probe(), the firmware is not
loaded to the device and the device is not fully activated. It is
not useful or sensible to do this full initialization on resume in
case it has not been previously initialized and is expected to be
in this initialized state.
Calling si2168_init() and therefore reading the firmware file for
the first time during resume leads to problems and should be avoided.
It is however safe to read the firmware file once it has already been
read outside of a suspend/resume situation.

Add a staus flag 'initialized' to store whether si2168_init() has
successfully been called. If initialization fails (e.g. due to missing
firmware file), the flag is not set.
Register a separate si2168_resume callback which only calls
si2168_init() once the 'initialized' flag has been set and it is safe
to load the firmware at resume.
The first call to si2168_init() will now always happen when the device
is actually used for the first time and never during resume.
This avoids the unsafe firmware file reading and should also speed up
resume by skipping unnecessary device initialization.

40ae6eff06 media: si2168: drop support for old firmware file name for si2168 B40
The si2168 B40 firmware file name has been changed in or before 2014.
During initialization, the new file name is preferred, but the old file
name is used as a fallback when request_firmware with the new file name
fails. Once reading the old file name has been attempted, only this name
will be used on further firmware loading attempts. During resume,
firmware reading with the new file name can (and likely will) fail even
when it actually exists. So this permanent switch to the fallback
firmware name happens even when not desired.

Any system using a recent kernel version can be expected to have the
firmware under the new name. The major distributions are either using
the dvb firmware collection from LibreELEC, which has the new firmware
file name, or do not package the firmware file but have documentation
pointing towards a manual installation of the firmware file under the
new name. If the firmware is available under the old name, it is
severely outdated. If the switch to the old file name is performed,
further firmware loading will either permanently fail (if it is not
available) or an outdated firmware version will be used.

Drop support for the fallback firmware file name and fail directly if
the firmware is not available under its current name. On following
attempts, the firmware read will then be retried with the correct
current name instead of the old name.

As reasoned above, there should be no negative effects of this change,
while simplifying code (the B40 variant will be handled identical
compared to the other variants of the si2168) and at the same time
fixing possible problems if firmware loading fails on resume.
