[PATCH 1/1] IDE: Deletion of an unnecessary check before the function call "module_put"

[SF Markus Elfring]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Fri, 21 Nov 2014 20:22:32 +0100

The module_put() 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.
