[PATCH 1/1] USB: serial: Deletion of an unnecessary check before the function call "release_firmware"

[SF Markus Elfring]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Fri, 21 Nov 2014 16:15:34 +0100

The release_firmware() 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.
