Subject: [PATCH 1/2] drm/msm/dsi: Delete an unnecessary check before the function
 call "dsi_destroy"

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Sat, 27 Jun 2015 22:05:31 +0200

The dsi_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.
