Is there a script for this? Anyway, I would say driver name is enough. 
Enough about the subject line ;-) I would like to give some general 
remarks as you seem to touch a lot of kernel code. First off, I think it 
is good to remove unused stuff. However, I would like some more 
explanation on your methodology apart from "partially found by using a 
static code analysis program". So a cover-letter explaining that would 
have been nice (maybe still is). Things like Kconfig option can affect 
whether function are used or not so how did you cover that.

Arend
