Subject: [PATCH 0/2] gigaset: more patches for 2.6.29

Dave,

following are two more patches for the Gigaset driver I'd like to see
included in release 2.6.29. Would you please take them through your
tree.

Thanks,
Tilman

Subject: [PATCH 1/2] 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.

Impact: some changed printk messages, no functional change
