Todo: - checkpatch.pl cleanups - sparse cleanups - lots of little modules, should be merged together and added to the build. - testing? - handle churn in v4l layer. Many thanks to Ross Cohen <rcohen@snurgle.org> for cleanup patches on this driver. Cc: Ross Cohen <rcohen@snurgle.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
