Subject: [PATCH 5/7] PM: sleep: core: Rename DPM_FLAG_NEVER_SKIP
Date: Fri, 10 Apr 2020 17:56:13 +0200	[thread overview]
Message-ID: <5092680.jloV5Ae5OO@kreacher> (raw)
In-Reply-To: <1888197.j9z7NJ8yPn@kreacher>

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

Rename DPM_FLAG_NEVER_SKIP to DPM_FLAG_NO_DIRECT_COMPLETE which
matches its purpose more closely.

No functional impact.
