[PATCH v3 3/3] drm: Convert users of drm_of_component_match_add to component_match_add_of
From: Sean Anderson
Date: Thu Jan 19 2023 - 14:15:36 EST
Every user of this function either uses component_compare_of or
something equivalent. Most of them immediately put the device node as
well. Convert these users to component_match_add_of and remove
drm_of_component_match_add.
