[PATCH] drm/bridge: ps8622: Delete an unnecessary check before backlight_device_unregister()

[SF Markus Elfring]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Fri, 22 Jul 2016 14:45:51 +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.
