"diff -Z" is used to trim the trailing whitespace when comparing the loaded firmware file with the source firmware file. However, per the comment in the source code, -Z should not be necessary. In testing, the input and output files are identical. Additionally, -Z is not a standard option and is not available in environments such as busybox. When -Z is not supported, diff fails with a usage error, which is suppressed, but then causes read_firmwares() to exit with a false failure message.

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.
