From bb2d43e0919ad89077dc756167c2bcc3e4cc97ab Mon Sep 17 00:00:00 2001 From: Markus Elfring Date: Fri, 21 Nov 2014 15:50:44 +0100 Subject: [PATCH] USB-SIS: Deletion of an unnecessary check before the function call "usb_put_dev" The usb_put_dev() 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.
