Subject: drm/armada: Introduce GEM object functions
X-Git-Tag: v5.11-rc1~206^2~15^2~193
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=ad01dd0376afbd7a39d78da543f5a048d4ae14c9;p=thirdparty%2Fkernel%2Flinux.git

drm/armada: Introduce GEM object functions

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