    rt2x00: Fix chipset revision validation · 755a957d
    Ivo van Doorn authored
    The validation of the chipset revision was broken
    since for rt2500usb and rt73usb different registers
    should be read. When rt2500usb was loaded for a rt73
    device it would false think the chipset was correct
    because the wrong register was read and validated.
    This has been fixed by expanding the check to also
    see if the first 4 bits of the revision is not-0
    (When reading the wrong register offset the returned
    value is usually 0 which can be interpreted as invalid)
