[PATCH 02/11] USB: dwc3: fix runtime pm imbalance on unbind

From: Johan Hovold
Date: Tue Apr 04 2023 - 03:26:02 EST


Make sure to balance the runtime PM usage count on driver unbind by
adding back the pm_runtime_allow() call that had been erroneously
removed.

Fixes: 266d0493900a ("usb: dwc3: core: don't trigger runtime pm when remove driver")
