usb: sl811-hcd: disable controller wakeup on remove
sl811h_probe() enables the HCD controller device as a wakeup source after
usb_add_hcd() succeeds, but sl811h_remove() removes the HCD and releases
the driver resources without disabling that wakeup source.
Disable controller wakeup after usb_remove_hcd() and before usb_put_hcd()
so the wakeup source object is detached while the controller device pointer
is still available.
This issue was identified during our ongoing static-analysis research while
reviewing kernel code.
