HID: wacom: Unregister sysfs attributes on remove
David Herrmann [Mon, 5 Sep 2011 16:45:29 +0000 (18:45 +0200)]
HID devices can be hotplugged so we should unregister all sysfs attributes when
removing a driver. Otherwise, manually unloading the wacom-driver will not
remove the sysfs attributes. Only when the device is disconnected, they are
removed, eventually.
