Subject: [PATCH 1/2] cpuidle: Don't pass any values to cpuidle_not_available
Date: Thu, 16 Mar 2023 15:37:11 +0900 [thread overview]
Message-ID: <20230316063712.33353-1-kazukih0205@gmail.com> (raw)
In-Reply-To: <linux-pm@vger.kernel.org>
There's no reason to pass any values to cpuidle_not_available() as the
function works standalone. Since we're planning to use the function in
other places, make it so to avoid code duplication.
