[PATCH v2 1/2] ARM: at91: fix system timer irq issue due to sparse irq support

From: Nicolas Ferre <hidden>
Date: 2012-08-23 09:57:19

On 08/14/2012 11:19 AM, ludovic.desroches at atmel.com :
From: Ludovic Desroches <redacted>

AT91_ID_SYS as virq is incorrect because of spare irq support which
introduces NR_IRQS_LEGACY offset.

Signed-off-by: Ludovic Desroches <redacted>
Tested-by: Joachim Eastwood <redacted>
Acked-by: Nicolas Ferre <redacted>

And pushed in at91-fixes branch for 3.6.
Thanks,
