09c41a23a2 media: Revert "media: vimc: propagate pixel format in the stream"
This reverts commit b6c61a6c37.

The requested pixelformat is being propagated from the capture to the
tpg in the sensor.

This was a bad design choice, as we start having the following issues:

* We set a pixelformat in the capture;
* We set matching media bus formats in the subdevices pads;
* Link validate looks fine (sizes matches, media bus formats matches);
* Issue: if some of the subdevice doesn't know how to generate the
requested pixelformat in the capture, then stream_on fails. This is bad
because capture says it supports that pixelformat, everything looks
fine, but it is not, and there is no way to find it out through the
links.

This patch was implemented so we could request any pixelformat from the
pipeline regardeless of the media bus format configured between pads.
Not all pixelformat can be mapped into a media bus code (e.g.
multiplanar formats), so with this patch we could request those
pixelformats from the tpg.

Solution: map pixelformats to media bus codes as before, and implement
conversions to other pixelformats in the capture to support multiplanar.

So first step to this solution is to revert this patch.

839b9d2c59 media: omap_vout: fix various v4l2-compliance failures
This patch fixes the following v4l2-compliance failures:

- FIELD_ANY could be returned, which is not allowed.
- JPEG colorspace was set instead of SRGB.
- No control events.
- Empty bus_info in QUERYCAP.
- Overlay format handling wasn't zeroing bitmap/clips and
  didn't return the chromakey correctly.
- G_FBUF didn't fill in many of the v4l2_framebuffer values.
  Now also return the base address of the corresponding
  framebuffer that this overlays.
- Missing ENUM/G/S_OUTPUT ioctls.
- ROTATE/VFLIP controls were added when the HW didn't support them.

With these changes 'v4l2-compliance' passes all non-streaming tests.

Tested on a Pandaboard and a Beagle XM board.

bfd77145f3 Makefile: Convert -Wimplicit-fallthrough=3 to just -Wimplicit-fallthrough for clang
A compilation -Wimplicit-fallthrough warning was enabled by commit
a035d552a9 ("Makefile: Globally enable fall-through warning")

Even though clang 10.0.0 does not currently support this warning without
a patch, clang currently does not support a value for this option.

  Link: https://bugs.llvm.org/show_bug.cgi?id=39382

The gcc default for this warning is 3 so removing the =3 has no effect
for gcc and enables the warning for patched versions of clang.

Also remove the =3 from an existing use in a parisc Makefile:
arch/parisc/math-emu/Makefile

 Two of these are for the habanalabs driver for issues found when running

 the fpga development tree.
 
 All of these have been in linux-next for a while with no reported

36e630ed98 Driver core fixes for 5.3-rc4
Here are 2 small fixes for some driver core issues that have been
 reported.  There is also a kernfs "fix" here, which was then reverted
 because it was found to cause problems in linux-next.
 
 The driver core fixes both resolve reported issues, one with gpioint
 stuff that showed up in 5.3-rc1, and the other finally (and hopefully)
 resolves a very long standing race when removing glue directories.  It's
 nice to get that issue finally resolved and the developers involved
 should be applauded for the persistence it took to get this patch
 finally accepted.
 
 All of these have been in linux-next for a while with no reported
 issues.  Well, the one reported issue, hence the revert :)

 The "biggest" one here is moving code from one file to another in order
 to fix a long-standing race condition with the creation of sysfs files
 for USB devices.  Turns out that there are now userspace tools out there
 that are hitting this long-known bug, so it's time to fix them.
 Thankfully the tool-maker in this case fixed the issue :)
 
 The other patches in here are all fixes for reported issues.  Now that
 syzbot knows how to fuzz USB drivers better, and is starting to now fuzz
 the userspace facing side of them at the same time, there will be more
 and more small fixes like these coming, which is a good thing.
