Rafael J. Wysocki 656088aa9b PCI / PM: Do not clear state_saved for devices that remain suspended
The state_saved flag should not be cleared in pci_pm_suspend() if the
given device is going to remain suspended, or the device's config
space will not be restored properly during the subsequent resume.

Namely, if the device is going to stay in suspend, both the late
and noirq callbacks return early for it, so if its state_saved flag
is cleared in pci_pm_suspend(), it will remain unset throughout the
remaining part of suspend and resume and pci_restore_state() called
for the device going forward will return without doing anything.

For this reason, change pci_pm_suspend() to only clear state_saved
if the given device is not going to remain suspended.  [This is
analogous to what commit ae860a19f3 (PCI / PM: Do not clear
state_saved in pci_pm_freeze() when smart suspend is set) did for
hibernation.]

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.
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.
