...set_lock_all is an evil hack and needs to be phased out. Two solutions: - We just update the lut after we've dropped the locks again in restore_fbdev_mode. - We need both a legacy path, in restore_fbdev_mode_legacy, and an atomic path in restore_fbdev_mode_atomic. The latter cannot use the gamme_set callback, since that would call drm_atomic_helper_legacy_gamma_set for atomic drivers, which would result in two calls to drm_atomic_commit in one critical sections. Instead that needs to open-code the logic in drm_atomic_helper_legacy_gamma_set and integrate it into the overall fbdev res...
