Subject: [PATCH v3 2/2] net: txgbe: fix to clear interrupt status after handling IRQ
GPIO EOI is not set to clear interrupt status after handling the
interrupt. It should be done in irq_chip->irq_ack, but this function
is not called in handle_nested_irq(). So executing function
txgbe_gpio_irq_ack() manually in txgbe_gpio_irq_handler().
Fixes: aefd013624a1 ("net: txgbe: use irq_domain for interrupt controller")
