ath9k: Delete an unnecessary check before the function call « relay_close »
Author: Markus Elfring <elfring@users.sourceforge.net>
The relay_close() 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.
