I restarted version numbering as this is meaningfully different from the previous set. pm_runtime_get_if_active() loses its second argument as it only made sense to have ign_usage_count argument true. The other change is also small but it has an effect on callers: pm_runtime_put_autosuspend() will, in the future, be re-purposed to include a call to pm_runtime_mark_last_busy() as well. Before this, current users of the function are moved to __pm_runtime_put_autosuspend() (added by this patchset) which will continue to have the current behaviour. I haven't included the conversion patches in this set as I only want to do that once this set has been approved and merged. The tree specific patches can be found here, on linux-next master (there are some V4L2 patches there, too, please ignore them for now): Later on, users calling pm_runtime_mark_last_busy() immediately followed by __pm_runtime_put_autosuspend() will be switched back to pm_runtime_put_autosuspend() once its behaviour change has been done (a patch near top of that branch). I'll provide these once the preceding ones have been merged. Comments are welcome. since v2: - Rebase on v6.8-rc1 (no changes). - Add Rodrigo's Reviewed-by: to the 1st patch. since v1: - patch 1: Rename __pm_runtime_get_conditional() as pm_runtime_get_conditional(). - patch 1: Reword documentation on driver use of pm_runtime_get_conditional().
