Commit12864ff854(ACPI / LPSS: Avoid PM quirks on suspend and resume from hibernation) bypasses lpss quirks for S3 and S4, by setting a flag for S3/S4 in acpi_lpss_suspend(), and check that flag in acpi_lpss_resume(). But this overlooks the boot case where acpi_lpss_resume() may get called without a corresponding acpi_lpss_suspend() having been called. Thus force setting the flag during boot.

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.
