I did run checkpatch, which warned about this, but that's a false 
positive to me.
The callback passed to CLK_OF_DECLARE() has a return type void, so 
there's no
way I can return -ENOMEM, and I don't want the error to be unnoticed.

About the other remarks - I agree with you, I'll fix these in the V2.

Thanks,
