Subject: [media] siano: unnecessary check before rc_unregister_device()
Author:  Markus Elfring <elfr...@users.sourceforge.net>
Date:    Mon Nov 24 18:32:30 2014 -0300

The rc_unregister_device() 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.
