This series addresses two problems in that arrangement: overwriting driver data belonging to the external PHY, and leaving phydev->drv pointing at freed converter memory after converter removal. Patch 1 retrieves the converter private data from its embedded phy_driver using container_of_const(), preserving the external PHY's MDIO driver-data field. It fixes the overwrite introduced by commit 168f7a161608 ("net: phy: gmii2rgmii: Dont use priv field in phy device"). Patch 2 stores private data on the converter's own MDIO device and adds a remove callback. It restores the original PHY driver under phydev->lock and releases the reference acquired by of_phy_find_device(). This addresses the stale pointer observed during PHY state-machine polling after converter-only unbind. The missing removal cleanup dates back to commit f411a6160bd4 ("net: phy: Add gmiitorgmii converter support"). Apply the patches in order.
