Hi,
Looks like commit 5de85b9d57ab ("PM / runtime: Re-init runtime
PM states at probe error and driver unbind") broke PM on at least
omap3. It seems we now need to additionally also call
pm_runtime_dont_use_autosuspend() to get things working again?
The following fixes idling on omap3, but I'm wondering if we
should do something in pm_runtime_reinit() instead?Oh one more thing, this happens as we get -EPROBE_DEFER with the regulators initially.
