From 331cb022d3ac1f85f7842a51495c33c629e947bc Mon Sep 17 00:00:00 2001 From: Dmitry Torokhov Date: Tue, 20 Apr 2010 22:06:53 -0700 Subject: [PATCH] Input: kbtab - simplify kbtab_disconnect() There is no need to check whether kbtab 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 kbtab_disconnect() since it is being called in kbtab_close().
