[17/80] ARM: OMAP: smartreflex: fix IRQ handling bug

[Greg KH]

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

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

From: Felipe Balbi <balbi@xxxxxx>

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.
