From 4ccfb98938e50133332ff22bb932d2f529f73738 Mon Sep 17 00:00:00 2001 From: Paul Cercueil Date: Tue, 28 Jun 2022 20:34:43 +0100 Subject: watchdog: dw_wdt: 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. 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.
