[libcamera-devel] [PATCH 2/2] tests: v4l2_compat: Check v4l2-compliance and v4l2-ctl versions

[Paul Elder]

v4l2-compliance and v4l2-ctl with version 1.20 and before will fail with
v4l2-compat. Check the versions of v4l2-compliance and v4l2-ctl before
continuing, though since neither of them currently are able to print
their version, simply checking if they can do so is sufficient.

Obviously this depends on v4l2-compliance and v4l2-ctl having --version,
so that needs to be accepted first before this can be merged.
