| |
Use the new pm_sleep_ptr() macro to handle the .suspend/.resume callbacks.
This macro 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.
