3.2-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Rafa�� Mi��ecki <zajec5@gmail.com>

commit cbbc0138efe1dcd5426b8fc5d87741f5057aee72 upstream.

We were using wrong IRQ number so clearing wasn't working at all.
Depending on a platform this could result in a one device having two
interrupts assigned. On BCM4706 this resulted in all IRQs being broken.
