He doesn't revert it after the patch series, but reverts it first
to then do it properly.  If you don't like that it's fine to ask
Bart to resend with a different patch ordering, but it would be really
helpful to do it politely.

Your original patch didn't use the alloc_session callback either,
so I don't really see the fuzz here.  I don't see how it makes things
clearer, but if you ask politely, and provide a detailed and valid
explanation I'm pretty sure Bart will adopt the series to your taste.

That patch doesn't work.  While it's great to have a maintainer that
sets overall architectural direction it also really helps to work nicely
with contributors that have detailed experience with the transport (or in
this case even wrote the original driver).

I think a lot of these disagreements could be sorted out much better if
you work with Bart at a technical level rather than having a personal
vandetta.
