Subject: [PATCH 4.9 10/43] rtmutex: Remove unused argument from rt_mutex_proxy_unlock()
Date: Mon, 8 Feb 2021 16:00:36 +0100 [thread overview]
Message-ID: <20210208145806.722848816@linuxfoundation.org> (raw)
In-Reply-To: <20210208145806.281758651@linuxfoundation.org>
From: Thomas Gleixner <tglx@linutronix.de>
[ Upstream commit 2156ac1934166d6deb6cd0f6ffc4c1076ec63697 ]
Nothing uses the argument. Remove it as preparation to use
pi_state_update_owner().
