The role of the s2idle_wakeup variable is to cause acpi_pm_wakeup_event() and acpi_pm_notify_handler() to increment pm_abort_suspend and trigger a wakeup from suspend-to-idle in case the ACPI SCI wakeup was canceled by acpi_s2idle_wake(). However, for this purpose it need not be set in acpi_s2idle_wake() and cleared in acpi_s2idle_sync(), respectively. In fact, it may be set as early as in acpi_s2idle_prepare() and cleared as late as in acpi_s2idle_restore(), so do that to allow subsequent changes to be simpler. This change is not expected to alter functionality. Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com> Acked-by: Thomas Gleixner <tglx@linutronix.de>
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.
