pci_pm_resume() and pci_pm_restore() call pci_pm_default_resume(), which
runs resume fixups before disabling wakeup events:
static void pci_pm_default_resume(struct pci_dev *pci_dev)
{
pci_fixup_device(pci_fixup_resume, pci_dev);
pci_enable_wake(pci_dev, PCI_D0, false);
}
pci_pm_runtime_resume() does both of these, but in the opposite order:
pci_enable_wake(pci_dev, PCI_D0, false);
pci_fixup_device(pci_fixup_resume, pci_dev);
We should always use the same ordering unless there's a reason to do
otherwise. Change pci_pm_runtime_resume() to call pci_pm_default_resume()
instead of open-coding this, so the fixups are always done before disabling
wakeup events.
pci_pm_default_resume() is called from pci_pm_runtime_resume(), which is
under #ifdef CONFIG_PM. If SUSPEND and HIBERNATION are disabled, PM_SLEEP
is disabled also, so move pci_pm_default_resume() from #ifdef
CONFIG_PM_SLEEP to #ifdef CONFIG_PM.

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.
