3.10-stable review patch. If anyone has any objections, please let me know.
------------------
From: Baruch Siach <baruch@tkos.co.il>
commit 1a33bd2be705cbb3f57d7223b60baea441039307 upstream.
irq_of_parse_and_map() returns 0 on error, while the code checks for NO_IRQ. This breaks on platforms that have NO_IRQ != 0.
