Subject: [PATCH 1/4] regulator fixed: Do not report enumaratable voltages if there are none
Date: Sat, 3 Mar 2012 12:40:01 +0100 [thread overview]
Message-ID: <1330774804-7310-2-git-send-email-s.hauer@pengutronix.de> (raw)
In-Reply-To: <1330774804-7310-1-git-send-email-s.hauer@pengutronix.de>
If used as a dummy voltage provider the fixed regulator should
not set n_voltages to make the core accept the device.
