[PATCH v1 10/12] drm/omapdrm: Use drm_bridge_funcs.atomic_check
Sam Ravnborg

Sun Jul 17 10:57:59 PDT 2022
Replace the deprecated drm_bridge_funcs.mode_fixup() with
drm_bridge_funcs.atomic_check().
drm_bridge_funcs.atomic_check() requires the atomic state operations,
update these to the default implementations.
Likewise update enable/disable to their atomic variants.
With these changes omapdrm now implement the full bridge atomic API.
