Subject: [PATCH 2/3] video/ssd1307fb: drop unneeded regulator NULL checks
Date: Mon, 2 Mar 2020 12:49:54 +0100 [thread overview]
Message-ID: <20200302114955.13897-2-a.fatoum@pengutronix.de> (raw)
In-Reply-To: <20200302114955.13897-1-a.fatoum@pengutronix.de>
regulator_{enable,disable} are already no-ops when the parameter is
NULL. Drop the NULL checks thusly.
