Subject: [PATCH] GPU-DRM-TTM: Delete an unnecessary check before the function
call "ttm_tt_destroy"
From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Mon, 16 Nov 2015 15:40:58 +0100
The ttm_tt_destroy() 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.
