Incorrect wording.
Maybe:
"It assumes that next request would ideally be of same size"

[Hemant] I have taken care of it in v3.

of same size.

Series applied without last patch (because must be reworked).

This series has a lot of cleanups. Starting from now, I will consider
NXP drivers as mature enough. I won't accept anymore such patch without
(or not enough) explanation.
For your users and readers, please start considering to explain
what was wrong and what needs to be changed.
Thanks
