Subject: drm: Reduce scope of 'state' variable
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=ac7c748317f515f426f48e72964c71142506f7a6;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

drm: Reduce scope of 'state' variable

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
