[PATCH] PM: sleep: Drop dev_pm_skip_next_resume_phases()

[PATCH] PM: sleep: Drop dev_pm_skip_next_resume_phases()

[Rafael J. Wysocki]

From: Rafael J. Wysocki <rafael.j.wysocki@intel.com>

After recent hibernation-related changes, there are no more callers
of dev_pm_skip_next_resume_phases() except for the PM core itself
in which it is more straightforward to run the statements from
that function directly, so do that and drop it.
