| |
Use the RUNTIME_PM_OPS() and pm_ptr() macros to handle the .runtime_suspend/.runtime_resume callbacks.
These macros allow the suspend and resume 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.
