[ Upstream commitb97760ae8e] Smatch complains about this condition: if (has_config && num_pins >= 1) The "has_config" variable is either uninitialized or true. The "num_pins" variable is unsigned and we verified that it is non-zero on the lines before so we know "num_pines >= 1" is true. Really, we could just check "num_configs" directly and remove the "has_config" variable.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
