The patch below was submitted to be applied to the 4.19-stable tree.
I fail to see how this patch meets the stable kernel rules as found at
Documentation/process/stable-kernel-rules.rst.
I could be totally wrong, and if so, please respond to
<stable(a)vger.kernel.org> and let me know why this patch should be
applied. Otherwise, it is now dropped from my patch queues, never to be
seen again.
thanks,

Subject: [PATCH] media: cec/v4l2: move V4L2 specific CEC functions to V4L2
Several CEC functions are actually specific for use with receivers,
i.e. they should be part of the V4L2 subsystem, not CEC.
These functions deal with validating and modifying EDIDs for (HDMI)
receivers, and they do not actually have anything to do with the CEC
subsystem and whether or not CEC is enabled. The problem was that if
the CEC_CORE config option was not set, then these functions would
become stubs, but that's not right: they should always be valid.
So replace the cec_ prefix by v4l2_ and move them to v4l2-dv-timings.c.
Update all drivers that call these accordingly.

Subject: [PATCH] media: em28xx: fix handler for vidioc_s_input()
The a->index is not the name of the internal amux entry,
but, instead a value from zero to the maximum number
of audio inputs.
As the actual available inputs depend on each board, build
it dynamically.
This is broken for a really long time. On a quick check,
since at least commit 195a4ef627e1 ("V4L/DVB (6585): Convert
em28xx to video_ioctl2") this was not implemented right.

Subject: [PATCH] media: em28xx: fix handler for vidioc_s_input()
The a->index is not the name of the internal amux entry,
but, instead a value from zero to the maximum number
of audio inputs.
As the actual available inputs depend on each board, build
it dynamically.
This is broken for a really long time. On a quick check,
since at least commit 195a4ef627e1 ("V4L/DVB (6585): Convert
em28xx to video_ioctl2") this was not implemented right.
