Format ioctls (Input 1) test Cropping failed on all devices running
4.19, 4.14, 4.9 and 4.4 kernel branches.

Format ioctls (Input 1):

...
test VIDIOC_G_SLICED_VBI_CAP: OK (Not Supported)
fail: ../../../v4l-utils-1.16.0/utils/v4l2-compliance/v4l2-test-formats.cpp(1425):
doioctl(node, VIDIOC_CROPCAP, &cap)
fail: ../../../v4l-utils-1.16.0/utils/v4l2-compliance/v4l2-test-formats.cpp(1447):

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

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

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.

Regards,
