From 4480c008047d72a7d40e1e7fdc1d3b420ebcb955 Mon Sep 17 00:00:00 2001 From: Marc Kleine-Budde Date: Fri, 20 Jul 2012 22:30:40 +0200 Subject: [PATCH] can: ems_usb: remove obsolete variable open_time The variable open_time in the struct ems_usb was used to protect ems_usb_set_mode() only to be called, if the interface is up. Now the CAN device infrastructure takes care of this.
