It's ok since i think there is no reason to have the two steps system ! it
doesn't make any sense to me ! prepare and commit are invoked consecutively 
one after the other for all mdo_ops and in every offload flow, with no extra
step in between! so it's totally redundant.

when i reviewed the series initially i was hesitant to check params 
on prepare step but i didn't see any reason since commit can still fail in
the firmware anyways and there is nothing we can do about it !
so we've decide to keep all the flows in one context for better readability
and since the prepare/commit phases are confusing.

I don't know, let's ask the original author, Antoine ?
