Commit 2b7ac0c87d98 ("tools: ynl-gen: don't touch the output file if
content is the same") is working too well. It was added so that
ynl-regen -f doesn't make us rebuild half of the kernel, if there
are no actual changes in any generated code.
When ynl-gen-c is called by make, however, we're better off trusting
make's tracking and overwrite the file. Otherwise if output is identical
we won't update file timestamps and make will retry code gen on every
invocation.

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.
