Just to be clear: you cherry-picked commit 8a7c5594c0202 (media: v4l2-ioctl: clear
fields in s_parm) for both 4.9 and 4.14, right?

If so, feel free to post that patch to the stable mailinglist for those kernels.
Make sure you CC me when you do that.

You probably need commit f63998331935 ([media] vivid: set V4L2_CAP_TIMEPERFRAME)
and possibly commit 3f122df4a2ba (media: vivid: do not implement VIDIOC_S_PARM for output streams).
