Thank-you very much for your comments in your reply.
Actually the patch did work - I confirmed it was run and the iomap
call was successful by adding a pr_info() after the pci_iomap()
success branch.
The only time I am getting the IRQ 17 nobody cared message is on
suspend / resume. A fresh boot a
wireless card, so theoretically
yes, but the right place to fix this is in the kernel since not
everyone is using grub.

Broadcom 4331 wireless cards built into Apple Macs unleash an IRQ storm

Further testing Broadcom 4331 reset quirk to prevent IRQ storm patch
testing reveals that:
1. quirk is run on initial boot up and this time appears to have
vastly reduced the interrupts (only 81 this time):
cat /proc/interrupts| grep 17

Sorry but testing the patch shows no difference.
I have just compiled debian jessie kernel 3.16.7-ckt25 and booted it
and hibernated it twice, then did the same with your patch applied.
There appeared to be no difference
On first boot I didn't get the nobody card disabling problem but

If no driver requested the shared interrupt yet, it should

That patch appears to be the grub 1 equivalent to grub2
git://git.savannah.gnu.org/grub.git rev 9d34bb8 which puts the network
device into D3 power state.
I am running grub2 with that patch and it doesn't fix my irq 17 problem.
Can we not fix this in grub2 via something like Lukas original patc

Wow, this is horrible.
This patch should help a bit.
