From 2a656cb5a4a3473c5fc6bf4fddc3560ceed53220 Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Thu, 2 May 2019 14:45:35 +0200 Subject: [PATCH] of: unittest: Remove error printing on OOM There is no need to print a backtrace or other error message if kzalloc(), kmemdup(), or devm_kzalloc() fails, as the memory allocation core already takes care of that.
