From d3f167aba99034929675a15535bcbd7deccf97bc Mon Sep 17 00:00:00 2001
From: Sebastian Andrzej Siewior <bigeasy@linutronix.de>
Date: Tue, 29 Sep 2020 16:32:49 +0200
Subject: [PATCH 063/191] locking/rtmutex: Move rt_mutex_init() outside of
CONFIG_DEBUG_RT_MUTEXES
rt_mutex_init() only initializes lockdep if CONFIG_DEBUG_RT_MUTEXES is
enabled. The static initializer (DEFINE_RT_MUTEX) does not have such a
restriction.
Move rt_mutex_init() outside of CONFIG_DEBUG_RT_MUTEXES.
Move the remaining functions in this CONFIG_DEBUG_RT_MUTEXES block to
the upper block.
