Subject: [PATCH 15/47] 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.
