rt2x00: Fix chipset detection for rt2500usb
The commit below changed the semantics of rt2x00_check_rev so that it no longer checked the bottom 4 bits of the rev were non-zero. During that conversion this part of the check was not propogated to the rt2500usb initialisation. commit 358623c22c9fd837b3b1b444377037f72553dc9f Author: Ivo van Doorn <ivdoorn@gmail.com> Date: Tue May 5 19:46:08 2009 +0200 rt2x00: Simplify rt2x00_check_rev Without this check rt73 devices are miss recognised as rt2500 devices and two drivers are loaded. Preventing the device being used. Reinstate this check. Signed-off-by: Andy Whitcroft <apw@canonical.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
