modules.order lists modules in the deterministic order (that is why
"modules order"), and there is no duplication in the list.
$(sort ) is pointless.

Isn't a subdirectory's modules.order just created by
concatenation of $(obj-m) (w/ respect to mentioned subdirs)?
Thus, "no duplication" seems to be true, as long as there is no obj-m
containing duplicated entries. Do we ensure unique entries in obj-m
only?
Kind regards,
Nicolas

Not $(obj-m) directly.
The magic is $^, which is a deduplicated list
of prerequisites.

The entries in modules.order must be unique.
Moreover, the basename of modules must be unique.
scripts/modules-check.sh is a stronger check.
