Subject: [PATCH 01/11] isdn/gigaset: adjust usb_gigaset tty write buffer limit

From: Tilman Schmidt <[email-masked]>
Date: Tue, 6 Jul 2010 02:18:37 +0200 (CEST)

The usb_gigaset driver's write buffer limit was different from those
of the others for no good reason. Set it to the same value, derived
from the Siemens documentation.

Impact: cosmetic
