Subject: [PATCH 24/28] mfd: sprd-sc27xx: Remove #ifdef guards for PM related functions
Date:   Sun,  7 Aug 2022 16:52:43 +0200
Message-Id: <20220807145247.46107-25-paul@crapouillou.net>
In-Reply-To: <20220807145247.46107-1-paul@crapouillou.net>

Precedence: bulk

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.

The advantage is then that these functions are now always compiled
independently of any Kconfig option, and thanks to that bugs and
regressions are easier to catch.
