[PATCH] mfd: Don't use NO_IRQ in WM8350

[Mark Brown <broonie@opensource.wolfsonmicro.com>]

NO_IRQ is only defined on some architectures - the general way to test
for an invalid IRQ in the modern kernel is by comparing with zero.

This is a build fix for platforms that don't define NO_IRQ (which is
most of them).  Please merge as soon as possible.
