Subject: [PATCH 4/7] isdn/gigaset: adjust usb_gigaset tty write buffer limit

From: Tilman Schmidt <[email-masked]>
Date: Sun, 23 May 2010 02:26:12 +0200 (CEST)

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

Impact: cosmetic
