commita6ff6cbf1f("usb: xhci: Add helper function xhci_set_power_on().") created a helper to control port power that needs to be called with xhci->lock held and interrupts disabled. It released the lock with spin_unlock_irqrestore using a new zero flag variable instead of the original 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:a6ff6cbf1f("usb: xhci: Add helper function xhci_set_power_on().")

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
