commitec6a75ef8eupstream. Previously, pci_pm_resume_noirq() cleared the PME Status bit in the Root Status register only if the device had no driver or the driver did not implement legacy power management. It should clear PME Status regardless of what sort of power management the driver supports, so do this before checking for legacy power management. This affects Root Ports and Root Complex Event Collectors, for which the usual driver is the PCIe portdrv, which implements new power management, so this change is just on principle, not to fix any actual defects.

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.
