| |
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.
