Subject: PM regression with commit 5de85b9d57ab PM runtime re-init in v4.5-rc1
Date: Tue, 26 Jan 2016 14:48:05 -0800	[thread overview]
Message-ID: <20160126224804.GB19432@atomide.com> (raw)

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?

Regards,

Tony
