Subject: [PATCH 1/3] drm/amd/powerplay/hwmgr: Delete an error message for a
 failed memory allocation in three functions

From: Markus Elfring <elfring@...rs.sourceforge.net>

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

This issue was detected by using the Coccinelle software.
