[PATCH 00/13] PM: runtime: Convert pm_runtime_put_autosuspend() and friends to a void function

[Brian Norris]

Similar to this effort:

  Subject: [PATCH v1 00/23] PM: runtime: Convert pm_runtime_put() to a void function
  https://lore.kernel.org/all/6245770.lOV4Wx5bFT@rafael.j.wysocki/

i.e., commit 3afd8df02433 ("PM: runtime: Change pm_runtime_put() return
type to void") and friends.

As with pm_runtime_put(), there is very little value in return-code
checking for any of the other async __pm_runtime_suspend() and
__pm_runtime_idle() APIs:

  pm_runtime_put_autosuspend()
  pm_request_idle()
  pm_request_autosuspend()

Checking the return code is more likely to
produce a race condition (fighting with user space writing "on" to the
"control" attribute) than to tell a consumer useful info.

Nobody outside KUnit tests checks pm_request_idle() or
pm_request_autosuspend() return codes, but there are a number of
pm_runtime_put_autosuspend() callers that check its return code. Thus,
this series largely deals with pm_runtime_put_autosuspend().

Patches 1-11 are independent of each other, and similarly to the last
series, I expect the respective maintainers can pick them up. We can
apply patch 12 later. Patch 13 is also independent, but included in this
topic for completeness. It can be applied any time.

This touches a lot of trees/maintainers, so I tried to keep CC's only
for the relevant patch(es), plus the cover letter. I hope that's not too
noisy.
