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.
