From 7f96b1caac43b34b325ee4acf61ce57d7214409c Mon Sep 17 00:00:00 2001 From: Ryan Mallon Date: Wed, 1 Apr 2009 20:33:30 +0100 Subject: [ARM] 5441/1: Use pr_err on error paths in at91 pm Change pr_debug to pr_err on error paths in the AT91 power management code. All of the errors will result in the cpu not going into the suspend state. This patch makes it possible to identify problems with suspend when power management debugging is not enabled.
