From: Rafael J. Wysocki <[email protected]> Note that after previous changes dpm_noirq_begin() and dpm_noirq_end() each have only one caller, so move the code from them to their respective callers and drop them.
Also note that dpm_noirq_resume_devices() and dpm_noirq_suspend_devices() need not be exported any more, so make them both static. This change is not expected to alter functionality.
