Removing the drm_bridge_remove call should avoid a NULL dereference during list processing in drm_bridge_remove if the error path is ever taken.
The more natural approach would perhaps be to add a drm_bridge_add, but there are several other bridges that never call drm_bridge_add. Just removing the drm_bridge_remove is the easier fix.
