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

[Ruan Jinjie <ruanjinjie@huawei.com>]

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.
