From c8770dcabd6a615b155c25dc4d57251d3e7f151c Mon Sep 17 00:00:00 2001 From: Tilman Schmidt Date: Fri, 26 Dec 2008 01:21:29 -0800 Subject: [PATCH] gigaset: use pr_err() and pr_info() Switch from private printk wrapper macros to using pr_err() and pr_info() from linux/kernel.h, at the same time unifying a few error messages.
