No macros like that. And honestly, why would you want a macro that is
more complicated than the operation itself?

But it sounds like what you actually want is just

     put_unaligned_le16(dum->devstatus, buf);

which does both bytes correctly (and turns into a plain 16-bit store
on sane architectures)..
