NAK.  Just because some variable isn't read doesn't mean that you need
to dream up some way to make it used.

In any case, this is wrong because it will duplicate this entry:

>  	orion_clkdev_add(NULL, "mv643xx_eth_port.0", ge);

which means that 'gephy' will probably be returned instead of 'ge' for
this device - and will cause the ethernet to stop working.

Please leave the code as it was and ignore this assigned-to-but-unused
variable.  Thanks.
