commit 4e5a04be88fe ("pinctrl: amd: disable and mask interrupts on probe")
was well intentioned to mask a firmware issue on a surface laptop, but it
has a few problems:
1. It had a bug in the loop handling for iteration 63 that lead to other
problems with GPIO0 handling.
2. It disables interrupts that are used internally by the SOC but masked
by default.
3. It masked a real firmware problem in some chromebooks that should have
been caught during development but wasn't.
There has been a lot of other development around s2idle; particularly
around handling of the spurious wakeups. If there is still a problem on
the original reported surface laptop it should be avoided by adding a quirk
to gpiolib-acpi for that system instead.

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.
