Commit Message

Dejin Zheng Jan. 8, 2020, 7:25 a.m. UTC
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.

Hi Dejin,

Thanks for reminding, This patch has been dropped, the patch V3 that replaced
it no longer contains this content, Please refer to
https://patchwork.ozlabs.org/patch/1219694/ for details. It should be fine after
giving up this commit.

Finally, Thanks a lot for Jose's help (Jose.Abreu@synopsys.com), he told me 
that the phy_mask is useful and should be kept when I submit this commit.

BR,
Dejin
