No need to initialize it since you're assigning to it right below.

dev_get_platdata will return NULL for DT, So this function will fail all the time.
Indeed, unless the probe() method assigns it from the 'data' field of 'struct of_device_id'.
How is it supposed to work? Am I missing some thing?
Look at stmmac_pltfr_probe().
