[PATCH 0/4] iio: fix PM-enable leak on probe error path across 4 drivers

[Stepan Ionichev]

This series fixes a class of runtime PM enable_count leaks on probe error
paths across drivers/iio/.

Each affected driver calls pm_runtime_enable() in probe and then a non-devm
registration function (typically iio_device_register()).  When the
registration fails the probe returns directly without calling
pm_runtime_disable(); on subsequent probe/rebind the runtime PM tracking
complains about an unbalanced enable.

The fix is the same in each driver: replace pm_runtime_enable() with
devm_pm_runtime_enable() and drop the now-redundant pm_runtime_disable()
and pm_runtime_set_suspended() calls in the .remove() callback.  The devm
action runs after .remove() and handles the teardown.

drivers/iio/adc/ti-ads1015.c was posted as a standalone patch earlier:
https://lore.kernel.org/all/20260529101011.3030-1-sozdayvek@xxxxxxxxx/

A separate follow-up will cover four more drivers (apds9960, mma8452,
pa12203001, us5182d) where the same leak exists but the probe error
path needs a goto to the existing manual cleanup label rather than a
plain return.
