From e848b583e03306f5f9b3a66a793c37e3649e04ca Mon Sep 17 00:00:00 2001 From: Jarek Poplawski Date: Mon, 11 Feb 2008 21:38:32 -0800 Subject: [AX25] ax25_ds_timer: use mod_timer instead of add_timer This patch changes current use of: init_timer(), add_timer() and del_timer() to setup_timer() with mod_timer(), which should be safer anyway.
