[PATCH 01/10] drm/modes: Move 3D stereo flag check into drm_mode_validate_basic()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx>

Currently we don't sanity check the 3D stereo flags for modes filled out
by the kernel. Move the check from drm_mode_convert_umode() into
drm_mode_validate_basic() so that we get the same check going both ways.
