[ Upstream commit 1be765b292577c752e0b87bf8c0e92aff6699d8e ] Fix for Thinkpad's with ECFW showing incorrect fan speed. Some models use decimal instead of hexadecimal for the speed stored in the EC registers. For example the rpm register will have 0x4200 instead of 0x1068, here the actual RPM is "4200" in decimal. Add a quirk to handle this.

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.
