Static analysis reports this problem
file.c:3206:2: warning: Undefined or garbage value returned to caller
return err;
^~~~~~~~~~
err is only set if there is some work to do. Because the loop returns
immediately on an error, if all the work was done, a 0 would be returned.
Instead of checking the unlikely case that there was no work to do,
change the return of err to 0.

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.
