Subject: [PATCH 01/14] of: Add of_property_write_string()
Date: Fri, 31 Mar 2017 07:33:10 +0200	[thread overview]
Message-ID: <20170331053323.17821-2-s.hauer@pengutronix.de> (raw)
In-Reply-To: <20170331053323.17821-1-s.hauer@pengutronix.de>

Setting a property to a string is used many times. Create a convenience
function for it.
