Chen Yu b00219888c ACPI: pfr_update: Fix the driver update version check 
commit 8151320c74 upstream.

The security-version-number check should be used rather
than the runtime version check for driver updates.

Otherwise, the firmware update would fail when the update binary had
a lower runtime version number than the current one.

Fixes: 0db89fa243 ("ACPI: Introduce Platform Firmware Runtime Update device driver")

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 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.
