Driver's and ->fill_modes functions are allowed to grab crtc mutexes (for e.g. load detect). Hence we need to first only grab the general kms mutex, and only in a second step grab all locks to do the modesets. This prevents a deadlock on my gm45 in the tv load detect code called by drm_helper_probe_single_connector_modes.
