SubjectRe: [PATCH 2/2] PM / Runtime: document autosuspend-helper side effects
* Johan Hovold <> [170410 04:41]:
> Document the fact that the autosuspend delay and enable helpers may
> change the power.usage_count and resume or suspend a device depending on
> the values of power.autosuspend_delay and power.use_autosuspend.
> Note that this means that a driver must disable autosuspend before
> disabling runtime pm on probe errors and on driver unbind if the device
> is to be suspended upon return (as a negative delay may otherwise keep
> the device resumed).
