From 5c040ea210185ce20f780906acca8231efa333b6 Mon Sep 17 00:00:00 2001 From: Paul Cercueil Date: Tue, 28 Jun 2022 20:34:46 +0100 Subject: [PATCH] watchdog: sama5d4_wdt: Remove #ifdef guards for PM related functions Use the new LATE_SYSTEM_SLEEP_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. Not using #ifdef guards means that the code is always compiled independently of any Kconfig option, and thanks to that bugs and regressions are easier to catch.
