[PATCH v2 03/21] drm/etnaviv: Introduce GEM object functions

Thomas Zimmermann
2020-09-15T23:01:43Z

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