[v3,7/8] drm: bridge: anx7625: Switch to devm_drm_of_get_bridge

Commit Message

Jagan Teki March 8, 2022, 8:27 a.m. UTC

devm_drm_of_get_bridge is capable of looking up the downstream
bridge and panel and trying to add a panel bridge if the panel
is found.

Replace explicit finding calls with devm_drm_of_get_bridge.
