Stephen Boyd 363c82a634 platform/chrome: cros_ec: Always expose last resume result 
[ Upstream commit 74bb746407 ]

The last resume result exposing logic in cros_ec_sleep_event()
incorrectly requires S0ix support, which doesn't work on ARM based
systems where S0ix doesn't exist. That's because cros_ec_sleep_event()
only reports the last resume result when the EC indicates the last sleep
event was an S0ix resume. On ARM systems, the last sleep event is always
S3 resume, but the EC can still detect sleep hang events in case some
other part of the AP is blocking sleep.

Always expose the last resume result if the EC supports it so that this
works on all devices regardless of S0ix support. This fixes sleep hang
detection on ARM based chromebooks like Trogdor.

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.
