From 4d8a6ae23af64a37803c0d15922819d27b4b8b08 Mon Sep 17 00:00:00 2001 From: Paul Cercueil Date: Sun, 23 Oct 2022 10:48:48 +0100 Subject: [PATCH] mfd: stmfx: Remove #ifdef guards for PM related functions Use the new DEFINE_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.
