Subject: [PATCH 5/9] intel_idle: Annotate init time data structures
Date: Thu, 13 Feb 2020 23:01:36 +0100	[thread overview]
Message-ID: <6952359.KTbxnIrxPq@kreacher> (raw)
In-Reply-To: <2960689.qre192dJKD@kreacher>

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

Add __initdata or __initconst annotations to the static data
structures that are only used during the initialization of the
driver.

No intentional functional impact.
