We'll use this for the compression control surface in i915. v2: Fix drm_get_format_info() kernel doc (Laurent) Don't pass 'dev' to the new hook (Laurent) v3: s/compresssion/compression/ (Ben) Cc: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Cc: Ben Widawsky <ben@bwidawsk.net> Cc: Jason Ekstrand <jason@jlekstrand.net> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by: Ben Widawsky <ben@bwidawsk.net> Link: http://patchwork.freedesktop.org/patch/msgid/20170321181218.10042-4-ville.syrjala@linux.intel.com
