Subject: [PATCH v2 0/7] media: v4l2: compat ioctl fixes
Date: Thu, 10 Jun 2021 23:42:58 +0200 [thread overview]
Message-ID: <20210610214305.4170835-1-arnd@kernel.org> (raw)
From: Arnd Bergmann <arnd@arndb.de>
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.
