Hi Greg,

you're right about that. I think I put a little too much effort in keeping old function names here.
I will get rid of that.

I also want to quote your previous E-Mail here:

Sorry, I didn't know about that particular script. I already put Patches 2, 3 and 4 through checkpatch.pl;
patch 1 is a little more to rework but I will, of course, do that.

Thanks,

Sven
