Could you explain the return values in more detail? Is this always a 3
element list or does it depend on the number of devices? What does it
look like with no multipath devices?

Thanks,

Yes,

it is always a tuple of 3 lists, the middle list is empty if there are no multipath devices found. I'll make sure to document it before pushing.
