events +even if it hasn't been opened. + +This is needed for devices that disconnects from the bus unless the +interrupt endpoint has been polled at least once or when not responding +to an input event (e.g. after having shut down X). + +Signed-off-by: Johan Hovold +Signed-off-by: Jiri Kosina +Signed-off-by: Greg Kroah-Hartman + +--- + drivers/hid/usbhid/hid-core.c | 26
