Date: Mon, 8 Aug 2022 19:40:47 +0200 From: Paul Cercueil <paul@...pouillou.net> To: Lee Jones <lee.jones@...aro.org> Cc: linux-kernel@...r.kernel.org, Paul Cercueil <paul@...pouillou.net> Subject: [PATCH v2 10/30] mfd: ucb1x00: 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.
