Nack. Say that in the error output.

Given this patch, checkpatch's message would be something like

"Deprecated use of 'v4l2_pipeline_pm_get', prefer '' instead"

Add something like "v4l2 runtime power management API" instead
At least point out what that is.

And in today's '-next' there's seems to be no indication in
documentation or code these calls are deprecated.
