Subject: [PATCH 4/4] state: Create alias in of_state_fixup()
Date: Thu, 4 May 2017 13:02:19 +0200 [thread overview]
Message-ID: <20170504110219.17929-5-s.hauer@pengutronix.de> (raw)
In-Reply-To: <20170504110219.17929-1-s.hauer@pengutronix.de>
When the kernel device tree is fixed up we assume that it doesn't
have a state node, so we must also assume that it doesn't have
a alias. Create it.
