A replacement also needs to quiesce the IRQ and delayed work before teardown. The IRQ path can hold an additional runtime-PM reference while a cable is present, and the PHY is already publicly registered by this point. Replacing only put_noidle() would not close those lifetime paths. I'll keep the current patch on hold while reworking the publication and cleanup ordering rather than resend the one-call substitution.
