[PATCH v3 0/2] Small runtime PM API changes

[Sakari Ailus <sakari.ailus@linux.intel.com>]

Hi folks,

Here's a small but a different set of patches for making two relatively
minor changes to runtime PM API. 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):
<URL:https://git.kernel.org/pub/scm/linux/kernel/git/sailus/linux-next.git/log/?h=pm>

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().
