Re: [PATCH 1/2] of: irq: Fix interrupt-map entry matching

[Tomasz Figa]

Hi Grant,

Could you pick this patch up? It fixes boot-up at least on several Exynos
based platforms, which use interrupt-map nodes with #interrupt-cells
higher than 1.

Also please disregard patch 2/2, as your fix that has been merged seems
to be fine.

Best regards,
Tomasz
