From 7ac2ed0ceeafa130f85aa947b271b571c68b9e75 Mon Sep 17 00:00:00 2001 From: Joe Perches Date: Thu, 25 Aug 2011 13:22:24 +0000 Subject: caif: Remove OOM messages, use kzalloc Remove per site OOM messages because they duplicate the generic mm subsystem OOM message. Use kzalloc instead of kmalloc/memset when next to the OOM message removals.
