From 5492f6f801c81c9663417cd8e48e759775977c83 Mon Sep 17 00:00:00 2001 From: Dmitry Torokhov Date: Tue, 20 Apr 2010 22:20:37 -0700 Subject: [PATCH] Input: acecad - simplify usb_acecad_disconnect() There is no need to check whether acecad structure is attached to the interface; if it isn't and we are called we have much bigger problems. Also no need to call usb_kill_urb() in usb_acecad_disconnect() since it is being called in usb_acecad_close().
