commit0665e38731upstream. Commita66d21d7db("usb: xhci: Add support for Renesas controller with memory") added renesas_usb_fw.mem firmware reference to xhci-pci. Thus modinfo indicates xhci-pci.ko has "firmware: renesas_usb_fw.mem". But the firmware is only actually used with CONFIG_USB_XHCI_PCI_RENESAS. An unusable firmware reference can trigger safety checkers which look for drivers with unmet firmware dependencies. Avoid referring to renesas_usb_fw.mem in circumstances when it cannot be loaded (when CONFIG_USB_XHCI_PCI_RENESAS isn't set).

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
