Subject[017/104] ARM: OMAP: smartreflex: fix IRQ handling bug
3.1-stable review patch.  If anyone has any objections, please let me know.

------------------
From: Felipe Balbi <balbi@ti.com>

commit 5a4f1844c2ba21f804d7729306d9b16eaeb724a8 upstream.

Fix a bug which has been on this driver since
it was added by the original commit 984aa6db
which would never clear IRQSTATUS bits.
