Re: [PATCH] PM / devfreq: Convert to DEFINE_SIMPLE_DEV_PM_OPS()

[sashiko-bot@kernel.org]

Thank you for your contribution! Sashiko AI review found 1 potential issue(s) to consider:
- [Low] The drivers incorrectly use `pm_sleep_ptr()` instead of `pm_ptr()` for assigning the `dev_pm_ops` structure pointer to the driver's `.pm` field.

PM / devfreq: Convert to DEFINE_SIMPLE_DEV_PM_OPS()

This commit converts the deprecated SIMPLE_DEV_PM_OPS to
DEFINE_SIMPLE_DEV_PM_OPS and drops __maybe_unused annotations. It also
updates the pm assignments to reduce kernel size when PM configs are
disabled.

[Severity: Low]
Should this use pm_ptr() instead of pm_sleep_ptr() for the structure pointer?
According to PM subsystem guidelines, pm_sleep_ptr() is intended for sleep
callbacks, while pm_ptr() should be used for the dev_pm_ops structure pointer
itself.

[Severity: Low]
Similar to the rk3399_dmc driver above, should this remain pm_ptr() for the
structure pointer instead of being changed to pm_sleep_ptr()?
