When receiving a disconnect event from the UDC, the mass storage function driver currently runs the handle_exception() routine asynchronously. For UDCs that support runtime PM, there is a possibility the UDC is already suspended by the time the do_set_interface() is executed. This can lead to HW register access while the UDC is already suspended.
