From 245cb473e5388fcbc01c7284b6a4e1446cdbf054 Mon Sep 17 00:00:00 2001 From: Paul Cercueil Date: Sun, 23 Oct 2022 10:48:30 +0100 Subject: mfd: pcf50633: Remove #ifdef guards for PM related functions Use the new EXPORT_GPL_SIMPLE_DEV_PM_OPS() and pm_sleep_ptr() macros to handle the .suspend/.resume callbacks. These macros allow the suspend and resume functions to be automatically dropped by the compiler when CONFIG_SUSPEND is disabled, without having to use #ifdef guards. This has the advantage of always compiling these functions in, independently of any Kconfig option. Thanks to that, bugs and other regressions are subsequently easier to catch.
