Clang static analysis returns this false positive thinkpad_acpi.c:8926:19: warning: The left operand of '!=' is a garbage value (status != 0) ? "enabled" : "disabled", status); ~~~~~~ ^ The return of fan_get_status* is checked inconsistenly. Sometime ret < 0 is an error, sometimes !ret. Both fan_get_status() and fan_get_status_safe() return 0 on success and return negative otherwise. Change the checks for error, ret < 0, into checks for not success, !ret.

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.
