Firstly, I am kind of curious why an 18 month old patch is getting
replied to now.   That aside, this interdependence between module.h and
init.h was reconsidered and you can see the resolution solution here:

https://lkml.kernel.org/r/1433276168-21550-1-git-send-email-paul.gortmaker@windriver.com

To summarize what is said there, yes - you can ignore the one line
removals for now.  We will revisit them after the above is merged.
