[PATCH 1/1] mISDN: Deletion of unnecessary checks before the function call "vfree"

[SF Markus Elfring]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Wed, 19 Nov 2014 20:48:26 +0100

The vfree() function performs also input parameter validation. Thus the test
around the call is not needed.

This issue was detected by using the Coccinelle software.
