I don't think this change is correct. With the old semantics, it was:

If we have CLK support, we expect there to be a clock for sata_mv, and
if there is no such clock, output a notice message, something is
probably wrong, i expected there to be a clock.

The new semantics are:

We expect there to be a clock for sata_mv, and if there is no such
clock, output a notice message, something is probably wrong, i
expected there to be a clock.

We are going to see this notice message much more, when it is not
expected.
