From fa5c0f46e2b9a1793313272fd19778fa2db92bf4 Mon Sep 17 00:00:00 2001 From: Marek Szyprowski Date: Thu, 19 Jan 2017 14:48:45 +0100 Subject: [PATCH] pinctrl: samsung: Remove messages for failed memory allocation Memory subsystem already prints message about failed memory allocation, there is no need to do it in the drivers.
