Subject: [PATCH v2 0/2] iio: fix bug with triggers not resuming after sleep

When a device enters an idle state (for example ASUS RC71L with s2idle)
and an iio driver has a trigger attached such as iio-trig-hrtimer,
after resuming the device the trigger is not triggering data acquisition.

This patch series solves the problem reliably and is well tested after
many cycles and many reboots.

Closes: https://lore.kernel.org/all/31d7f7aa-e834-4fd0-a66a-e0ff528425dc@gmail.com/

Changelog:
- V2: patch 2:
        + Simpliy code
        + Remove unneeded code protections around SET_RUNTIME_PM_OPS()
        + pm_ptr() to let the compiler drop bmi323_core_pm_ops if !CONFIG_PM
