[PATCH 1/2] drm/tilcdc: Delete an error message for a failed memory allocation in seven functions

[SF Markus Elfring]

From: Markus Elfring <elfr...@users.sourceforge.net>
Date: Tue, 6 Feb 2018 21:51:15 +0100

Omit an extra message for a memory allocation failure in these functions.

This issue was detected by using the Coccinelle software.
