Use the priv field in mdio device structure instead of the one in
phy device structure. The phy device priv field may be used by the
external phy driver and should not be overwritten.
Hi Harini

I _think_ you could use dev_set_drvdata(&mdiodev->dev) in xgmiitorgmii_probe() and
dev_get_drvdata(&phydev->mdiomdio.dev) in _read_status()
Thanks for the review. This works if I do:
dev_set_drvdata(&priv->phy_dev->mdio.dev->dev) in probe
and then
dev_get_drvdata(&phydev->mdio.dev) in _read_status()

i.e mdiodev in gmii2rgmii probe and priv->phy_dev->mdio are not the same.

If this is acceptable, I can send a v2.
Hi Harini

I think this is better, making use of the central driver
infrastructure, rather than inventing something new.

The kernel does have a few helper, spi_get_drvdata, pci_get_drvdata,
hci_get_drvdata. So maybe had add phydev_get_drvdata(struct phy_device
*phydev)?

	Thanks
