[PATCH v2 4/8] drm: bridge: dw-mipi-dsi: Switch to devm_drm_of_get_bridge

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
