[PATCH 4/8] drm: Allow drm_mode_object_find() to look up an object of any type

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

 



From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx>

To avoid having to pass object types from userspace for atomic mode
setting ioctl, allow drm_mode_object_find() to look up an object of any
type. This will only work as long as the all object types share the ID
space.
