[PATCH v2 08/21] drm/msm: Introduce GEM object funcs

Thomas Zimmermann
2020-09-15T23:01:31Z

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