[v3,04/22] drm/exynos: Introduce GEM object functions

Commit Message

Thomas Zimmermann Sept. 23, 2020, 10:21 a.m. UTC

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