* Johan Hovold <johan@kernel.org> [170410 04:41]: > Update the autosuspend documentation which claimed that the autosuspend > delay is not taken into account when using the non-autosuspend helper > functions, something which is no longer true since commit d66e6db28df3 > ("PM / Runtime: Respect autosuspend when idle triggers suspend"). > > This specifically means that drivers must now disable autosuspend before > disabling runtime pm in probe error paths and remove callbacks if > pm_runtime_put_sync was being used to suspend the device before > returning. (If an idle callback can prevent suspend, > pm_runtime_put_sync_suspend must be used instead of pm_runtime_put_sync > as before.) > > Also remove the claim that the autosuspend helpers behave "just like > the non-autosuspend counterparts", something which have never really > been true as some of the latter use idle notifications. > > Signed-off-by: Johan Hovold <johan@kernel.org>
