Subject: [PATCH v2 6/9] PM: sleep: core: Rename dev_pm_smart_suspend_and_suspended()
Date: Sat, 18 Apr 2020 18:52:48 +0200 [thread overview]
Message-ID: <4560390.sSGzV6Abg1@kreacher> (raw)
In-Reply-To: <5673945.BT02kTCndr@kreacher>
From: "Rafael J. Wysocki" <rafael.j.wysocki@intel.com>
Because all callers of dev_pm_smart_suspend_and_suspended use it only
for checking whether or not to skip driver suspend callbacks for a
device, rename it to dev_pm_skip_suspend() in analogy with
dev_pm_skip_resume().
No functional impact.
