Mathias Nyman 02e3263600 xhci: fix runtime pm enabling for quirky Intel hosts
commit 024d411e9c5d49eb96c825af52a3ce2682895676 upstream.

Intel hosts that need the XHCI_PME_STUCK_QUIRK flag should enable
runtime pm by calling xhci_pme_acpi_rtd3_enable() before
usb_hcd_pci_probe() calls pci_dev_run_wake().
Otherwise usage count for the device won't be decreased, and runtime
suspend is prevented.

usb_hcd_pci_probe() only decreases the usage count if device can
generate run-time wake-up events, i.e. when pci_dev_run_wake()
returns true.

This issue was exposed by pci_dev_run_wake() change in
commit 8feaec33b9 ("PCI / PM: Always check PME wakeup capability for
runtime wakeup support")
and should be backported to kernels with that change

README

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.
