Re: [PATCH] usb: dwc3: Properly handle processing of pending events

If dwc3 is runtime suspended we defer processing the event buffer until resume, by setting the pending_events flag. Set this flag before triggering resume to avoid race with the runtime resume callback.

While handling the pending events, in addition to checking the event buffer we also need to process it. Handle this by explicitly calling dwc3_thread_interrupt(). Also balance the runtime pm get() operation that triggered this processing.
