Subject: [PATCH v3 21/28] mfd: max77686: Remove #ifdef guards for PM related functions
Date:   Sun, 23 Oct 2022 10:48:45 +0100
Message-Id: <20221023094852.8035-22-paul@crapouillou.net>
In-Reply-To: <20221023094852.8035-1-paul@crapouillou.net>

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.
