Dear Jeff, David:

This patch:

    Fix IRQ handle bug when interrupt mode.

    The driver was incorrectly handled and returned IRQ_HANDLED
    while the device is not generating the interrupt.
    It happened due to faulty determination of interrupt status register.

    The patch is also available at:
