Subject: [PATCH 07/42] state: open code state_backend_init in caller
Date: Fri, 31 Mar 2017 09:03:11 +0200	[thread overview]
Message-ID: <20170331070346.26878-8-s.hauer@pengutronix.de> (raw)
In-Reply-To: <20170331070346.26878-1-s.hauer@pengutronix.de>

Safes a lot of argument passing to a function that is used
only once.
