3.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Alexander Shishkin <alexander.shishkin@xxxxxxxxxxxxxxx>
commit 0c3f3dc68bb6e6950e8cd7851e7778c550e8dfb4 upstream.
Re-enable chipidea irq even if there's no role changing to do. This is
a problem since b183c19f ("USB: chipidea: re-order irq handling to avoid
unhandled irqs"); when it manifests, chipidea irq gets disabled for good.
