Commit ef4c6270bf28 made the check of whether struct_mutex is held more verbose, and this triggers a warning when calling drm_gem_object_unreference() from tegra_gem_set_tiling() which does not acquire that lock.
Use drm_gem_object_unreference_unlocked() instead to ensure locking is handled correctly.
