[PATCH 1/2 net-next] net: ll_temac: Fix an NULL vs IS_ERR() check in temac_open()

[Dan Carpenter]

The phy_connect() function doesn't return NULL pointers.  It returns
error pointers on error, so I have updated the check.

[PATCH 2/2 net-next] net: ll_temac: remove an unnecessary condition

[Dan Carpenter]

The "pdata->mdio_bus_id" is unsigned so this condition is always true.
This patch just removes it.
