Format ioctls (Input 1):

There is no easy patch you can backport to fix this and I wouldn't bother with this.

Test passes on mainline, -next and 5.0 Test failed on 4.19, 4.14, 4.9 and 4.4 for all devices

steps to reproduce:

   # boot 4.19/4.14/4.9 kernel on x86_64 / Juno / hikey /  device
   #  install v4l-utils package
   # modprobe vivid.ko no_error_inj=1
   # v4l2-compliance -v -d /dev/video0

Be aware that v4l2-compliance is meant to be compiled directly from the v4l-utils master repo, and run against the latest media-tree master repository. It's not meant to be backwards compatible with older kernels.

If you want to do regression testing with v4l2-compliance against older kernels, then it would actually be better to pick a v4l2-compliance version from around the time that kernel version was first released.
