[ Upstream commit 780feae7eb69388c8d8b661cda6706b0dc0f642b ]
Fix coccinelle warning:
./drivers/net/phy/mdio_bus.c:51:5-12: ERROR: PTR_ERR applied after initialization to constant on line 44 ./drivers/net/phy/mdio_bus.c:52:5-12: ERROR: PTR_ERR applied after initialization to constant on line 44
fix this by using IS_ERR before PTR_ERR
