typo: properly

But more usefully, I don't think it should be needed -- we don't use
__must_check at all in uapi includes; if this is needed that means some
of the include here uses the kernel internal includes and that shouldn't
be needed as they're not normally installed.

Didn't actually try to see but taking the compilation line that fails
and running it with -E will probably show where that must_check comes
from
