From 8fe9f659b730ca92367370cf7ae6de6ef640cf62 Mon Sep 17 00:00:00 2001 From: Felipe Balbi Date: Wed, 23 Nov 2011 14:43:37 -0800 Subject: ARM: OMAP: smartreflex: fix IRQ handling bug 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.
