Hi Mike,
That's what I'm going to do for v2, except for the comments in
habanalabs.h, which we made sure are written according to kernel-doc.
I promise that we will go over the entire code and make everything
kernel-doc compatible (I'm opening a jira ticket now :) ) but it may
take a couple of weeks or more.

In any case, I fixed all of your other comments for this patch.
Thanks,
Oded
