Not a problem with merging cleanups in general. We have several out of
tree patches but doesn't make sense to to wait.
I wasn't in cc for the series but I don't like this change to be the
part of cleanup series.

	mac = of_get_mac_address(np);
 	if (mac)
-		memcpy(bp->dev->dev_addr, mac, ETH_ALEN);
+		ether_addr_copy(bp->dev->dev_addr, mac);
 	else

Also extending scope of variables is not the right way to go. Especially
when some automation tools are reporting that you should reduce scope of
use for them. Wolfram is checking it for example.

Thanks,
