From 6579e57b31d79d31d9b806e41ba48774e73257dc Mon Sep 17 00:00:00 2001 From: Arjan van de Ven Date: Mon, 21 Jul 2008 13:31:48 -0700 Subject: net: Print the module name as part of the watchdog message As suggested by Dave: This patch adds a function to get the driver name from a struct net_device, and consequently uses this in the watchdog timeout handler to print as part of the message.
