Johan Hovold aeb4db8ab7 PM: sleep: wakeirq: fix wake irq arming 
[ Upstream commit 8527beb120 ]

The decision whether to enable a wake irq during suspend can not be done
based on the runtime PM state directly as a driver may use wake irqs
without implementing runtime PM. Such drivers specifically leave the
state set to the default 'suspended' and the wake irq is thus never
enabled at suspend.

Add a new wake irq flag to track whether a dedicated wake irq has been
enabled at runtime suspend and therefore must not be enabled at system
suspend.

Note that pm_runtime_enabled() can not be used as runtime PM is always
disabled during late suspend.

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.
