Greetings!!

IBM CI has reported build failure of 20260122 on IBM Power server.


Error:


ERROR: modpost: "phy_get_rx_polarity" [drivers/net/phy/
air_en8811h.ko] undefined!
ERROR: modpost: "phy_get_tx_polarity" [drivers/net/phy/

Thanks for the config file.

The probleme is because allthough CONFIG_PHY_COMMON_PROPS is selected,
drivers/phy/phy-common-props.o is not built because CONFIG_GENERIC_PHY
is not selected.

Likely comes from commit 66d8a334b57e ("net: phy: air_en8811h: deprecate
"airoha,pnswap-rx" and "airoha,pnswap-tx"")

Christophe

The intention was for drivers/phy/phy-common-props.o to be
buildable/usable without CONFIG_GENERIC_PHY.

Does this help?

Yes it fixes the build for me.
