3.0-stable review patch. If anyone has any objections, please let us know.
------------------
From: Len Brown <len.brown@intel.com>
commit 17edf2d79f1ea6dfdb4c444801d928953b9f98d6 upstream.
Fix the printk_once() so that it actually prints (didn't print before due to a stray comma.)
[ hpa: changed to an incremental patch and adjusted the description accordingly. ]
