Subject[RFC PATCH net-next 6/9] net: pcs: lynx: Remove lynx_get_mdio_device and lynx_pcs_destroy
Date
The PCS subsystem now manages getting/putting the PCS device. We can
convert our manual cleanup with a call to pcs_put. This removes the last
users of lynx_get_mdio_device lynx_pcs_destroy, so they can be removed.
