rt2x00: Simplify rt2x00_check_rev
rt2x00_check_rev() was too specific for rt2500usb and rt73usb, by adding the mask argument (instead of hardcoding it into the function itself) we can use the function in rt2800usb as well. v2: Fix revision mask for rt2800usb Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W.
