maintainerThe 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 <[email protected]> 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.
