From 2c8ea46d3e5462c54120f6bca42e2ccee4e48904 Mon Sep 17 00:00:00 2001 From: Stephen Boyd Date: Wed, 28 Dec 2016 14:56:58 -0800 Subject: [PATCH] usb: chipidea: msm: Mark device as runtime pm active We're not properly marking the glue layer/wrapper device as runtime active, so runtime PM believes that the hardware state is inactive when we call pm_runtime_enable() in this driver. This causes a problem when the glue layer has a power domain associated with it, because runtime PM will go and disable the power domain to match the 'inactive' state of the device. Let's mark the device as active so that runtime PM doesn't improperly power down this device when it's actually active.
