Seems inappropriate that this fix is within this patch series?

otoh I assume dax_add_host() has never failed so it doesn't matter much.

The series seems useful but is at v4 without much sign of review
activity. I think I'll take silence as assent and shall slam it all
into -next and see who shouts at me.
