From 0c3f3dc68bb6e6950e8cd7851e7778c550e8dfb4 Mon Sep 17 00:00:00 2001 From: Alexander Shishkin Date: Tue, 11 Jun 2013 13:41:48 +0300 Subject: [PATCH] usb: chipidea: fix id change handling 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.
