Linux kernel source tree
b288420e77
Some ThinkPad models, like the X1 Tablet 1st and 2nd Gen, are passively cooled without any fan. Currently, an entry in /proc/acpi/ibm/fan is nevertheless created, and misleadingly shows status: enabled speed: 65535 level: auto This patch adds a TPACPI_FAN_NOFAN quirk definition and corresponding handling to not initialize a fan interface at all. For the time being, the quirk is only applied for X1 Tablet 2nd Gen (types 20JB, 20JC; EC N1O...); further models (such as Gen1, types 20GG and 20GH) can be added easily once tested. Tested on a 20JCS00C00, BIOS N1OET58W (1.43), EC N1OHT34W.

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.
