I had no idea this exists, thanks a lot for this TIL :-)

I guess the issue here is that this exists, yay, but it's not documented
with the other here:

https://dri.freedesktop.org/docs/drm/doc-guide/kernel-doc.html#structure-union-and-enumeration-documentation

I guess a patch to kernel-doc.rst would be great. Adding some kernel-doc
folks.

Ok I went ahead and typed that patch (just we don't waste effort),
just waiting for the sphinx build to finish to make sure it looks nice
before I send out the patch.

Could you please also add documentation for function-like macros,
since that's also missing? With that acked-by: me.

This is already present:

Function documentation
----------------------

The general format of a function and function-like macro kernel-doc comment is::

  /**
   * function_name() - Brief description of function.
   * @arg1: Describe the first argument.
   * @arg2: Describe the second argument.
   *        One can provide multiple line descriptions
   *        for arguments.


but the way that you did it makes sense also.

Ah missed that it includes wording for function-like macros. On your
patch as-is:
