Subject: [PATCH 2/2] of: unittest: Remove bogus overlay mutex release from overlay_data_add()
Date: Mon, 27 Nov 2017 15:46:27 +0100 [thread overview]
Message-ID: <1511793987-315-3-git-send-email-geert+renesas@glider.be> (raw)
In-Reply-To: <1511793987-315-1-git-send-email-geert+renesas-gXvu3+zWzMSzQB+pC5nmwQ@public.gmane.org>
overlay_data_add() never takes the special overlay mutex, so it must not
be released in the error patch.
Presumably the call to of_overlay_mutex_unlock() is a relic from v1 of
the patch.
Fixes: f948d6d8b792bb90 ("of: overlay: avoid race condition between applying multiple overlays")
