[PATCH] video: fbdev: omap2: displays-new: Delete a check before backlight_device_unregister()

[SF Markus Elfring]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Sun, 28 Jun 2015 14:30:17 +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.
