From: Paul Cercueil Date: Tue, 28 Jun 2022 19:34:45 +0000 (+0100) Subject: watchdog: s3c2410_wdt: Remove #ifdef guards for PM related functions X-Git-Tag: v6.1-rc5~648^2~12 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=aa55761ab442f71cd4dded60f55bbd90a3c904af;p=platform%2Fkernel%2Flinux-starfive.git watchdog: s3c2410_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.
