From 255f5c327ec3a1d77fe54ef5773ef5eaf7c35a3e Mon Sep 17 00:00:00 2001 From: Ian Munsie Date: Thu, 11 Mar 2010 12:07:25 +0000 Subject: [PATCH] i4l: change magic numbers in Eicon DIVA ISDN driver to symbolic names 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.
