Subject: [PATCH net-next 0/3] net: Fix return value check for get_phy_device()

The get_phy_device() function returns error pointers and never
returns NULL. Update the checks accordingly.

And get_phy_device() returns -EIO on bus access error and -ENOMEM
on kzalloc failure in addition to -ENODEV, return PTR_ERR is more
sensible.

  net: mdio: Fix return value check for get_phy_device()
  amd-xgbe: Return proper error code for get_phy_device()
  net: hisilicon: hns: Fix return value check for get_phy_device()
