    drm/udl: Make sure to get correct endian keys from vendor descriptor · d42f0349

    from udlfb to udl kms driver.
    
    The driver was not using le16_to_cpu when reading keys from the vendor
    descriptor, causing incorrect parsing. Mainly, sku_pixel_limit was not
    being parsed on big-endian systems. This would result in a blank screen
    on big-endian CPUs where the DL chips's max mode was smaller than the
    monitor's native mode.
