Subject: [PATCH 3/4] gigaset: reduce syslog clutter
From: Tilman Schmidt <tilman@...p.cc>
Subject: [PATCH 3/4] gigaset: reduce syslog clutter
Improve readability of the Gigaset driver's kernel messages by
removing a few unnecessary messages and limiting the emission
of some debug messages more narrowly.
Impact: logging
