Rafael J. Wysocki 443046d1ad PM: sleep: Make suspend of devices more asynchronous
In analogy with previous changes, make device_suspend_late() and
device_suspend_noirq() start the async suspend of the device's parent
after the device itself has been processed and make dpm_suspend_late()
and dpm_noirq_suspend_devices() start processing "async" leaf devices
(that is, devices without children) upfront so they don't need to wait
for the other devices they don't depend on.

This change reduces the total duration of device suspend on some systems
measurably, but not significantly.

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 reStructuredText 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.
