Subject: [PATCH v2] drm: Reduce scope of 'state' variable
Date: Thu, 15 Jun 2017 16:04:36 +0200	[thread overview]
Message-ID: <20170615140436.GA9939@gmail.com> (raw)

Smaller scope reduces visibility of variable and makes usage of
uninitialized variable less possible.

Changes in v2:
	- separate declaration and initialization
