Subject: [patch 3/3] i4l: change magic numbers in Eicon DIVA ISDN driver to symbolic names
From: Ian Munsie <imunsie@...ibm.com>
Replace references to the '20' magic number found throughout the Eicon
ISDN driver for the length of the station_id field in the T30_INFO struct
with the T30_MAX_STATION_ID_LENGTH symbolic constant.
