Subject: [PATCH] net: ucc_geth: Don't use the MAC as PHY without a fixed link
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
This matches what the other drivers using fixed-link support do and
restores the behaviour before commit 87009814cdbb ("ucc_geth: use the
new fixed PHY helpers") for the affected device trees (i.e. no
phy-handle and no fixed-link).
Fixes: 87009814cdbb ("ucc_geth: use the new fixed PHY helpers")
