Then change that last paragraph. You could say something like this:

To keep the cases where port 5 isn't controlled by phylink working as
before, we need to preserve the mt7530_setup_port5() call from mt7530_setup().

I think it's a case of saying too much, which sparks too many unresolved
questions in the reader's mind, which are irrelevant for the purpose of
this specific change: eliminating the overlap between DSA's setup() time
and phylink.
