From 33777e6676ca60652bd48c7867641fb779106909 Mon Sep 17 00:00:00 2001 From: Brian Norris Date: Thu, 2 May 2013 14:18:51 -0700 Subject: mtd: tests: don't print error messages when out-of-memory These strings are now unnecessary and discouraged in the kernel. The kernel will have plenty of big scary messages if kmalloc fails. These now only serve to bloat the module.
