From 42255927e832f9c1ed8db4e84530bc6a54aa2fee Mon Sep 17 00:00:00 2001 From: Lee Jones Date: Thu, 4 Feb 2021 17:29:00 +0000 Subject: rtmutex: Remove unused argument from rt_mutex_proxy_unlock() From: Thomas Gleixner [ Upstream commit 2156ac1934166d6deb6cd0f6ffc4c1076ec63697 ] Nothing uses the argument. Remove it as preparation to use pi_state_update_owner().
