It relased the lock with spin_unlock_irqerstore using a new zero flag variable instead of the origial flag from spin_lock_irqsave. This regression triggered a static checker warning about bogus flags, and a null pointer dereference on armada-385. Fix it by passing a pointer to the correct flags and using it instead Fixes: a6ff6cbf1fab ("usb: xhci: Add helper function xhci_set_power_on().")
