While I note the way you're saying this given the widespread adoption I
think there's a bit more effort needed on making sure people are aware
of this model and that it's possible to do it - most of the APIs with
devres support really ought to have things like a devm_clk_get_enable()
(an example discussed further up the thread) added to them.

devres has been quite widely adopted but not in a way that supports this
usage model.
