[PATCH] iio: cros_ec: Convert to DEFINE_SIMPLE_DEV_PM_OPS()

[PATCH] iio: cros_ec: Convert to DEFINE_SIMPLE_DEV_PM_OPS()

[Triet Hoang]

Convert the deprecated SIMPLE_DEV_PM_OPS
to DEFINE_SIMPLE_DEV_PM_OPS and pm_sleep_ptr().

This lets us drop the __maybe_unused annotations
from the resume callbacks, and reduces kernel size
in case CONFIG_PM or CONFIG_PM_SLEEP is disabled.

I think we should use EXPORT_GPL_SIMPLE_DEV_PM_OPS here.
Should I send the v2 patch to correct it?

There is room on the lines to make them longer a bit.

  Convert the deprecated SIMPLE_DEV_PM_OPS to DEFINE_SIMPLE_DEV_PM_OPS
  and pm_sleep_ptr().

  This lets us drop the __maybe_unused annotations from the resume callbacks,
  and reduces kernel size in case CONFIG_PM or CONFIG_PM_SLEEP is disabled.

There is a macro that combines DEFINE + EXPORT.

Please do.  Though normal process is to wait a few more days
first to see if you get any other feedback that can be incorporated
into v2.

[PATCH v2] iio: cros_ec: Convert to DEFINE_SIMPLE_DEV_PM_OPS()

Convert deprecated SIMPLE_DEV_PM_OPS to DEFINE_SIMPLE_DEV_PM_OPS
and pm_sleep_ptr().

This lets us drop the __maybe_unused annotations from the resume callbacks,
and reduces kernel size when CONFIG_PM or CONFIG_PM_SLEEP is disabled.

This needs to update accordingly: SIMPLE_DEV_PM_OPS() + EXPORT_SYMBOL_GPL()

Not really, the __maybe_unused is done in a way that _object_ size is bigger
(function is compiled), but since it's put in a separate section, linker will
drop it as unused, so the resulting binary will not have it.

...

Code wise looks good to me.

Convert deprecated SIMPLE_DEV_PM_OPS() to DEFINE_SIMPLE_DEV_PM_OPS()

This lets us drop the __maybe_unused annotations from the resume callback.

Please don't send a new version as a reply to the previous version, it can
break tooling like b4. Additionally, please wait at least 24 hours before
sending a new version.

Please drop it for now until they are resolved.
