From 758f46c2e67c4901ea49e684e12adb698b1b2bbd Mon Sep 17 00:00:00 2001 From: Paul Cercueil Date: Thu, 20 Oct 2022 19:50:47 +0100 Subject: watchdog: kempld: Remove #ifdef guards for PM related functions Use the pm_ptr() macro to handle the .suspend/.resume callbacks. This macro allows 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.
