From: Wan Ahmad Zainie <wan.ahmad.zainie.wan.mohamad@xxxxxxxxx>
Add missing pm_runtime_disable() to remove(), in order to avoid
an Unbalanced pm_runtime_enable when the module is removed and
re-probed.
Error log:
root@intel-corei7-64:~# modprobe -r intel_xhci_usb_role_switch
root@intel-corei7-64:~# modprobe intel_xhci_usb_role_switch
intel_xhci_usb_sw intel_xhci_usb_sw: Unbalanced pm_runtime_enable!
