[PATCH v2 13/21] drm/rockchip: Convert to drm_gem_object_funcs

Thomas Zimmermann
2020-09-15T23:01:36Z

GEM object functions deprecate several similar callback interfaces in
struct drm_driver. This patch replaces the per-driver callbacks with
per-instance callbacks in rockchip. The only exception is gem_prime_mmap,
which is non-trivial to convert.
