Subject: [PATCH] drm/panel: simple: Remove unneeded gpiod NULL check
Date: Sun, 16 Jul 2017 21:05:39 -0300	[thread overview]
Message-ID: <1500249939-8075-1-git-send-email-festevam@gmail.com> (raw)

From: Fabio Estevam <fabio.estevam@nxp.com>

The gpiod API checks for NULL descriptors, so there is no need to
duplicate the check in the driver.
