[PATCH-next 19/20] gpio: gpio-omap: irq_startup() must not return error codes

From: Russell King <rmk+kernel@armlinux.org.uk>

The irq_startup() method returns an unsigned int, but in __irq_startup()
it is assigned to an int. However, nothing checks for errors, so any
error that is returned is ignored.

Remove the check for GPIO-input mode and the error return.
