Subject: [PATCH] genirq: export handle_bad_irq

A cleanup of the omap gpio driver introduced a use of the
handle_bad_irq() function in a device driver that can be
a loadable module.

This broke the ARM allmodconfig build:

ERROR: "handle_bad_irq" [drivers/gpio/gpio-omap.ko] undefined!

This patch exports the handle_bad_irq symbol in order to
allow the use in modules.

Signed-off-by: Arnd Bergmann <arnd@...db.de>
Fixes: 450fa54cfd66 ("gpio: omap: convert to use generic irq handler")
