I agree that above code should clear both. Just wanna verify. Have
you tested it and/or do you have any information confirming this? If
we don't have any further info, I think we should read PORT_SLOT_STAT
before clearing PORT_IRQ_STAT to be on the safe side.
I've implemented the clear_irq() function to clear all interrupts as you
said, but haven't had time to test this thoroughly. Ultimately, we
don't know if it works until we experience real errors and see how the
system responds.
I don't think it matters in which order you do things, as long as you
allow for the fact that reading PORT_SLOT_STAT will clear the command
completion interrupt flag.
