[PATCH v2 2/2] net: stmmac: remove the useless member phy_mask

From: Dejin Zheng
Date: Wed Jan 08 2020 - 02:26:49 EST


The value of phy_mask in struct stmmac_mdio_bus_data will be passed
to phy_mask of struct mii_bus before register mdiobus, the mii_bus
was obtained by mdiobus_alloc() and set mii_bus->phy_mask as zero
by default. the stmmac_mdio_bus_data->phy_mask also set zero when
got stmmac_mdio_bus_data by devm_kzalloc(), so doesn't need to pass
the value and remove the useless member phy_mask in the struct
stmmac_mdio_bus_data.
