[PATCH v2 14/21] drm/tegra: Introduce GEM object functions

Thomas Zimmermann tzimmermann at suse.de
Tue Sep 15 14:59:51 UTC 2020


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