GPU-DRM-OMAP: Delete unnecessary checks before two function calls
The following functions test whether their argument is NULL and then return immediately. * backlight_device_unregister * drm_gem_object_unreference_unlocked Thus the test around the calls is not needed. This issue was detected by using the Coccinelle software.
