From: Arnd Bergmann <arnd@xxxxxxxx>
There was a report from Syzbot a while ago that I tried fixed earlier,
but my fix did not get picked up because of a merge conflict with
another patch I had in my tree.
I finally managed to take a close enough look at the merge conflict
to figure out that the subdev driver handling for VIDIOC_DQEVENT_TIME32
was wrong in all combinations of the patches and just needs to be
removed. In the process I also came across a couple of other issues,
so the series has now grown to seven patches.
I have done randconfig build testing and found no compile time issues,
but the driver specific patches have not been tested so far.
