Subject: [PATCH] PM: runtime: Replace pm_runtime_callbacks_present()
Date: Thu, 28 May 2020 16:45:14 +0200 [thread overview]
Message-ID: <2735489.s4WY8YHBoM@kreacher> (raw)
From: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
The name of pm_runtime_callbacks_present() is confusing, because
it suggests that the device has PM-runtime callbacks if 'true' is
returned by that function, but in fact that may not be the case,
so replace it with pm_runtime_has_no_callbacks() which is not
ambiguous.
No functional impact.
