From a8ca2efce43f81153b81c712f7d8faf7666f55cc Mon Sep 17 00:00:00 2001 From: Marc Kleine-Budde Date: Tue, 4 Mar 2014 22:00:47 +0100 Subject: [PATCH] can: janz-ican3: convert dev_ printing to netdev_ This patch converts the dev_ printing to netdev_, this makes it possible to remove the "struct device *dev" pointer from the "struct ican3_dev".
