[PATCH v2 00/17] iio: Stop looking at pm_runtime_put_autosuspend() return codes

[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 pm_runtime_put_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.

Because the IIO subsystem has the bulk of drivers that inspect
pm_runtime_put_autosuspend(), and because those drivers have a lot of
other issues touching the same code (which Jonathan suggested [1] I
fix -- I fix some, but not all), I'm sending an IIO-specific series
under a v2 label (since many of the changes are still borrowed from the
earlier series).

For reference, the larger v1 series can be found at [2].

Changes in v2:
 * Split iio into its own series
 * Split into per-driver patches
 * Fix various usage bugs in these iio drivers in the adjacent code
 * Remove now-unnecessary helpers
 * Maintain Reviewed-by from v1 for drivers where there was no
   additional change (aside from splitting up patches)
