I believe it still has not been answered why this can't be pushed into
resource providers (clock, regulators, gpio, interrupts, etc),
especially for devm APIs where we know exactly what device we are
requesting a resource for, so that individual drivers do not need to
change anything. We can mark the device as being probed so that probe
deferral is only handled when we actually execute probe() (and for the
bonus points scream loudly if someone tries to return -EPROBE_DEFER
outside of probe path).

And now with coccinelle script we can expect a deluge of patches
reshuffling drivers...

Thanks.
