[PATCH 14/28] mfd: sm501: Remove #ifdef guards for PM related functions

From: Paul Cercueil
Date: Sun Aug 07 2022 - 10:55:21 EST


Use the new pm_sleep_ptr() macro to handle the .suspend/.resume
callbacks.

This macro allow the suspend and resume functions to be automatically
dropped by the compiler when CONFIG_SUSPEND is disabled, without having
to use #ifdef guards.

The advantage is then that these functions are now always compiled
independently of any Kconfig option, and thanks to that bugs and
regressions are easier to catch.
