In the general case, a driver doesn't know which of system shutdown or reboot is the better action to take to protect hardware in an emergency situation. For this reason, hw_protection_shutdown is going to be removed in favor of hw_protection_trigger, which defaults to shutdown, but may be configured at kernel runtime to be a reboot instead. The ChromeOS EC situation is different as we do know that shutdown is the correct action as the EC is programmed to force reset after the short period, thus replace hw_protection_shutdown with __hw_protection_trigger with HWPROT_ACT_SHUTDOWN as argument to maintain the same behavior. No functional change.

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 reStructuredText 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.
