Subject: [PATCH] usb: dwc3: turn off VBUS when leaving host mode
VBUS should be turned off when leaving the host mode.
Set GCTL_PRTCAP to device mode in teardown to de-assert DRVVBUS pin to
turn off VBUS power.
Fixes: 5f94adfeed97 ("usb: dwc3: core: refactor mode initialization to its own function")

That piece of code just moved around a bit, fixed up and queued for 4.9.
