[PATCH linux-next] irq: export handle_fasteoi_irq

[Vincent Stehlé]

Export handle_fasteoi_irq to be able to use it in e.g. the Zynq gpio driver
since commit 6dd859508336 ("gpio: zynq: Fix IRQ handlers").

This fixes the following link issue:

  ERROR: "handle_fasteoi_irq" [drivers/gpio/gpio-zynq.ko] undefined!

Hi,

This can be seen in Linux next-20140822 with e.g. arm allmodconfig.

Zync gpio seems to be the first code to use handle_fasteoi_irq, which can be
compiled as a module.

Best regards,

V.

I saw the same thing here and came up with the same fix.
