[PATCH v2 12/21] drm/radeon: Introduce GEM object functions

Thomas Zimmermann
2020-09-15T23:01:35Z

GEM object functions deprecate several similar callback interfaces in
struct drm_driver. This patch replaces the per-driver callbacks with
per-instance callbacks in radeon.

v2:
* move object-function instance to radeon_gem.c (Christian)
* set callbacks in radeon_gem_object_create() (Christian)
