From cfb725275ea25857e8f0e3bf358fff7c84cc787c Mon Sep 17 00:00:00 2001

Subject: [PATCH 12/35] MIPS: ath79: fix a wrong IRQ number
The Ubiquiti XM board setup code uses an invalid
IRQ number, because it if above of NR_IRQS. This
leads to failed 'request_irq' calls:
ath9k 0000:00:00.0: request_irq failed
ath9k: probe of 0000:00:00.0 failed with error -22
Preserve some IRQ numbers for the built-in IRQ
controller of PCI host controllers in the
AR71XX/AR724X SoCs, and use the correct IRQ
number in the board setup code.
Signed-off-by: Gabor Juhos <juhosg@openwrt.org>
v2: - no changes
The IRQ controller code is also missing, that will be
added in a separate patch.
