drm: Remove linux/media-bus-format.h from drm_crtc.h

2022-07-05T18:15:13+00:00

drm_crtc.h has no need for linux/media-bus-format.h, so don't include it. Avoids useless rebuilds of the entire universe when touching linux/media-bus-format.h. Quite a few placs do currently depend on linux/media-bus-format.h without actually including it directly. All of those need to be fixed up. v2: Deal with ingenic as well v3: Fix up mxsfb and remaining parts of imx Acked-by: Sam Ravnborg Acked-by: Jani Nikula Signed-off-by: Ville Syrjälä Link: https://patchwork.freedesktop.org/patch/msgid/20220630195114.17407-4-ville.syrjala@linux.intel.com
