hd64465_ss & hd64461_ss

[Kristoffer E. <kri...@gm...>]

Greetings,

Just starting looking at pcmcia code again. When compairing to hd64465 code I found this segment:

static void hs_mask_and_ack_irq(unsigned int irq)
{
	hs_socket_disable_ireq(hs_mapped_irq[irq].sock);
        if (hs_mapped_irq[irq].old_handler != &no_irq_type)
	    hs_mapped_irq[irq].chip->ack(irq);
}

Now, it says as a comment that this was used to get rid of some unexpected IRQ complaints. Im experiencing same issues with my hd64461 driver and been bugtracking this for a couple of weeks.

I just can't understand why that code should be needed for hd64465 || hd64461? Could someone please put that code in a situation were it actually would make some good.

To make the context clear:
pcmcia driver uses IRQ 78
pcmcia_card gets IRQ 79
All interrupts are 78 and then demux translates them into pcmcia slot OR pcmcia card interrupt.
