A static checker gave the following warnings: drivers/edac/sb_edac.c:1030 ibridge_get_ha() warn: signedness bug returning '(-22)' drivers/edac/sb_edac.c:1037 knl_get_ha() warn: signedness bug returning '(-22)' Both because the functions are declared to return a "u8", but try to return -EINVAL for the error case. Fix by returning 0xff (since the caller doesn't look at, or pass on, the return value).

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.
