  Print error message for potential EPROBE_DEFER error using
dev_err_probe, which captures the reason in
/sys/kernel/debug/devices_deferred and otherwise silences
the message.

This doesn't apply against current code, please check and resend.

That's expected. Patch 2 changes the dev parameter of dev_err(),
which is being changed to dev_err_probe() in this patch.

I think we are getting too close to the merge window for this
series considering it's touching so many subsystems. But you
can take patch 2 + 11 to the regulators tree as is.

Thanks for the review,
