[Sergei Shtylyov]

Hello.

   Here's the set of 3 patches against DaveM's 'net-next.git' repo. They deal
with some error checks in the device tree MDIO code...

[1/3] of_mdio: mdio_device_create() never returns NULL
[2/3] of_mdio: use IS_ERR_OR_NULL()
[3/3] of_mdio: use PTR_ERR_OR_ZERO()

MBR, Sergei
