[PATCH 1/2] gigaset: use pr_err() and pr_info()

From: Tilman Schmidt
Date: Tue Dec 23 2008 - 04:38:12 EST


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.

Impact: some changed printk messages, no functional change
