This driver obtains a bridge pointer from of_drm_find_bridge() in the probe function and stores it until driver removal. of_drm_find_bridge() is deprecated. Move to devm_drm_of_find_bridge() which puts the bridge reference on remove or on probe failure.
Note: this driver stores the bridge pointer in the adv_bridge global variable, which could hold a value from a previous probe. However the code flow always sets the adv_bridge value in the probe function before it is read, so the change is safe.
