[PATCH v3] drm: Reduce scope of 'state' variable

From: Dawid Kurek
Date: Thu Jun 15 2017 - 13:46:08 EST


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
