From: Colin Ian King <colin.k...@canonical.com>
Currently the null check logic on dwc->usb_psy is inverted as it allows
calls to power_supply_put with a null dwc->usb_psy causing a null
pointer dereference. Fix this by removing the ! operator.
Addresses-Coverity: ("Dereference after null check")
Fixes: 59fa3def35de ("usb: dwc3: add a power supply for current control")
