Subject: [PATCH] omapfb: panel-dsi-cm: Delete an unnecessary check before backlight_device_unregister()
Date: Sat, 23 Jul 2016 19:37:14 +0200 [thread overview]
Message-ID: <1c53beae-e516-f208-935e-2a49416ce075@users.sourceforge.net> (raw)
In-Reply-To: <5317A59D.4@users.sourceforge.net>
From: Markus Elfring <elfring@users.sourceforge.net>
Date: Sat, 23 Jul 2016 19:29:28 +0200
The backlight_device_unregister() function tests whether its argument
is NULL and then returns immediately.
Thus the test around the call is not needed.
This issue was detected by using the Coccinelle software.
