What about if Brian made sure to just fully copy the latest version of
"cros_ec_commands.h" from the EC codebase and changed this commit
message to say:

Copy the latest version of "cros_ec_commands.h" from the Chrome OS EC
code base, which is the source of truth for this file. See
<https://chromium.googlesource.com/chromiumos/platform/ec/+/master/include/ec_commands.h>.

From the commit message it would be clear that this is an external
file linked into the kernel for convenience.

In general requesting that code from outside the kernel conform to
"kerneldoc" seems like a bit of a stretch. In general having some
type of parse-able format for comments is nice, but I could see that
in the Chrome OS EC codebase it would be a bit overkill.


Also: it would be awfully strange if we suddenly started changing the
coding convention of this file or we had half the file in one
convention and half in another. The rest of this file is in EC
convention and it seems sane to keep it that way...
