[PATCH 1/1] x86: PCI-Calgary: Deletion of an unnecessary check before the function call "free_tce_table"

[SF Markus Elfring]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Sat, 22 Nov 2014 12:55:28 +0100

The free_tce_table() 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.
