commit e112e593b215c394c0303dbf0534db0928e87967
Author: Nicolas Iooss <nicolas.iooss_linux@xxxxxxx>

drm: use dev_name as default unique name in drm_dev_alloc()
we're using a reasonable default which should work for everyone. Only
mtk, rcar-du and sun4i are affected, and as kms-only drivers without
any rendering support no one should ever care about the unique name
v2: Rebase on top of mediatek.
