Subject[PATCH v2 21/30] mfd: arizona: Remove #ifdef guards for PM related functions
Date
Use the new EXPORT_GPL_DEV_PM_OPS() and pm_ptr() macros to handle the PM
callbacks.

These macros allow the PM functions to be automatically dropped by the
compiler when CONFIG_PM 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.
