Series media: v4l2: simplify compat ioctl handling | expand

Commit Message

Arnd Bergmann Sept. 17, 2020, 3:28 p.m. UTC 
Now that the 'clips' array is accessed by common code in the native
ioctl handler, the same can be done for the compat version, greatly
simplifying the compat code for these four ioctl commands.
