[ Upstream commit 0e71862a20d58b6e8d4c39de1d72c8919c4dccd1 ]
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().
