Subject: [PATCH] drm: Reduce scope of 'state' variable
Git-commit: ac7c748317f515f426f48e72964c71142506f7a6
Patch-mainline: v4.13-rc1
References: FATE#322643 bsc#1055900
Smaller scope reduces visibility of variable and makes usage of
uninitialized variable less possible.
Changes in v2:
- separate declaration and initialization
Changes in v3:
- add missing signed-off-by tag
