Thanks for tracking this down, and thanks to Andrew for confirming the missing prerequisite. Queued 1bc80d673087 for 6.18.y, 6.12.y, 6.6.y, 6.1.y and 5.15.y. On 6.1.y and 5.15.y it also needed its own prerequisite 31605c01fb24 ("phy: mscc: Use PHY_ID_MATCH_VENDOR to minimize PHY ID table"), which I've queued there as well. -- Thanks, Sasha
