Subject: [PATCH 01/10] locking/rtmutex: Remove Comparison to bool
Date: Fri, 27 Mar 2020 21:23:48 +0000 [thread overview]
Message-ID: <20200327212358.5752-2-jbi.octave@gmail.com> (raw)
In-Reply-To: <20200327212358.5752-1-jbi.octave@gmail.com>
From: Jules Irenge <jbi.octave@example.com>
Coccinelle reports a warning inside rt_mutex_slowunlock()
WARNING: Comparison to bool
To fix this, the comparison to bool is removed
This not only fixes the issue but also removes the unnecessary comparison.
Remove comparison to bool
