The kbuild bot recently added the W=1 option, which triggered
documentation cleanups to squelch hundreds of kernel-doc warnings.

To make sure new kernel contributions don't add regressions to
kernel-doc descriptors, this patch suggests an option to treat
warnings as errors in CI/automated tests. A command-line option is
provided to the kernel-doc script, as well as a check on environment
variables to turn this optional behavior on.

Examples for the two subsystems I contribute to:

KCFLAGS="-Wall -Werror" make W=1 sound/
KCFLAGS="-Wall -Werror" make W=1 drivers/soundwire/

Randy Dunlap also suggested adding a log for when generating
documentation. The documentation build is however not stopped for now.

KDOC_WERROR=1 make htmldocs

So I'm not opposed to this, but I'm missing a couple of things in the
changelog:

 - A statement that you are adding a -Werror option that invokes this
   behavior.

 - Mention of the fact that you also cause it to look at a couple of
   environment variables and change its behavior based on that.

Could I get a version with that clarified a bit?

Thanks,
