commit e112e593b215c394c0303dbf0534db0928e87967 Author: Nicolas Iooss nicolas.iooss_linux@m4x.org Date: Fri Dec 11 11:20:28 2015 +0100
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.
