[Fiona] shouldn't you return -ENOTSUP?

[Adam] All other errors end with returning -1 (see the ret_status variable which is initialized to -1).
That's why I handle the error case the same way. This is inside the test suite, not a PMD.

[Fiona] ok, can see in the code that the capability is already checked at the higher level
for this case, so no need to return ENOTSUP here. -1 is ok
