Subject: [PATCH 16/28] mfd: tps6586x: Remove #ifdef guards for PM related functions
Date:   Sun,  7 Aug 2022 16:52:35 +0200

Use the new pm_sleep_ptr() macro to handle the .irq_set_wake() callback.

This macro allows the mt6397_irq_set_wake() function 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.
