Despite being big, the changes here are trivial: they just change the
probing method for I2C. So, apply it as a merge.

KASAN reports a use-after-free:

 dvb_dmxdev_init+0x2af/0x4a0 [dvb_core]
 vidtv_bridge_probe+0x766/0xa40 [dvb_vidtv_bridge]
 ...

It is because the error handling in vidtv_bridge_dvb_init() is wrong.

First, vidtv_bridge_dmx(dev)_init() will clean themselves when fail, but
goto fail_dmx(_dev): calls release functions again, which causes
use-after-free.

Also, in fail_fe, fail_tuner_probe and fail_demod_probe, j = i will cause
out-of-bound when i finished its loop (i == NUM_FE). And the loop
releasing is wrong, although now NUM_FE is 1 so it won't cause problem.

Fix this by correctly releasing everything.

<title>media: visl: add virtual stateless decoder driver</title>

<id>urn:sha1:0c078e310b6d16b9b9489bbc7bc1476430d19a7c</id>
<content type='text'>
A virtual stateless device for stateless uAPI development purposes.

This tool's objective is to help the development and testing of
userspace applications that use the V4L2 stateless API to decode media.

A userspace implementation can use visl to run a decoding loop even when
no hardware is available or when the kernel uAPI for the codec has not
been upstreamed yet. This can reveal bugs at an early stage.

This driver can also trace the contents of the V4L2 controls submitted
to it.  It can also dump the contents of the vb2 buffers through a
debugfs interface. This is in many ways similar to the tracing
infrastructure available for other popular encode/decode APIs out there
and can help develop a userspace application by using another (working)
one as a reference.

Note that no actual decoding of video frames is performed by visl. The
V4L2 test pattern generator is used to write various debug information
to the capture buffers instead.

In vimc_init(), when platform_driver_register(&amp;vimc_pdrv) fails,
platform_driver_unregister(&amp;vimc_pdrv) is wrongly called rather than
platform_device_unregister(&amp;vimc_pdev), which causes kernel warning:

 Unexpected driver unregister!
