Subject: [PATCH net-next v2 2/3] net: phy: Uniform PHY driver access

struct phy_device contains a pointer to the PHY driver and nearly
everywhere this pointer is used to access the PHY driver. Only
mdio_bus_phy_may_suspend() is still using to_phy_driver() instead of the
PHY driver pointer. Uniform PHY driver access by eliminating
to_phy_driver() use in mdio_bus_phy_may_suspend().

Only phy_bus_match() and phy_probe() are still using to_phy_driver(),
because PHY driver pointer is not available there.
