[PATCH 5/7] drm/plane-helper: Export individual helpers
Thomas Zimmermann
tzimmermann at suse.de
Wed Jul 20 08:30:56 UTC 2022
Export the individual plane helpers that make up the plane functions and
align the naming with other helpers. The plane helpers are for non-atomic
modesetting and exporting them will simplify a later conversion of drivers
to atomic modesetting.
With struct drm_plane_funcs removed from drm_plane_helper.h, also remove
the include statements. It only needs linux/types.h for uint32_t and a
number of forward declarations.
