drm: bridge: Return NULL on error from drm_bridge_get_edid()

Browse source

The drm_bridge_get_edid() function is documented to return an error
pointer on error. The underlying .get_edid() operation, however, returns
NULL on error, and so do the drm_get_edid() and drm_do_get_edid()
functions upon which .get_edid() is usually implemented. Make
drm_bridge_get_edid() return NULL on error to be consistent.
