Delete that.

Not that it's really related to this one patch, but why is a GPIO number named
"irq" in client->irq??

It gets ever more confused as you're seemingly converting an IRQ to
an IRQ. Can we rename this variable in a separate patch?
Apart from this it looks good, but do I dare apply it without applying
3/4 (that needs ACK:ing)?
