Hans de Goede 767191db82 platform/x86: intel_int0002_vgpio: Use acpi_register_wakeup_handler() 
The Power Management Events (PMEs) the INT0002 driver listens for get
signalled by the Power Management Controller (PMC) using the same IRQ
as used for the ACPI SCI.

Since commit fdde0ff859 ("ACPI: PM: s2idle: Prevent spurious SCIs from
waking up the system") the SCI triggering, without there being a wakeup
cause recognized by the ACPI sleep code, will no longer wakeup the system.

This breaks PMEs / wakeups signalled to the INT0002 driver, the system
never leaves the s2idle_loop() now.

Use acpi_register_wakeup_handler() to register a function which checks
the GPE0a_STS register for a PME and trigger a wakeup when a PME has
been signalled.

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.
