Yeah, we can live without that for a while. In any case, the patch that
fixes it is this one:

	3d9bfb19bd70 ("scripts/kernel-doc: Fix struct and struct field attribute processing")

I'm enclosing it as a reference (as seen at Jon's docs-next tree). It is
probably worth to just wait for Jon's pull request.

Thanks,
Mauro

Subject: [PATCH] scripts/kernel-doc: Fix struct and struct field attribute
 processing

The kernel-doc attempts to clear the struct and struct member attributes
from the API documentation it produces. It falls short of the job in the
following respects:

- extra whitespaces are left where __attribute__((...)) was removed,

- only a single attribute is removed per struct,

- attributes (such as aligned) containing numbers were not removed,

- attributes are only cleared from struct fields, not structs themselves.

This patch addresses these issues by removing the attributes.
