Subject: [PATCH AUTOSEL 5.2 018/249] batman-adv: fix for leaked TVLV handler.
Date: Mon, 15 Jul 2019 09:31:59 -0400	[thread overview]
Message-ID: <20190715133550.1772-18-sashal@kernel.org> (raw)
In-Reply-To: <20190715133550.1772-1-sashal@kernel.org>

From: Jeremy Sowden <jeremy@azazel.net>

[ Upstream commit 17f78dd1bd624a4dd78ed5db3284a63ee807fcc3 ]

A handler for BATADV_TVLV_ROAM was being registered when the
translation-table was initialized, but not unregistered when the
translation-table was freed.  Unregister it.

Fixes: 122edaa05940 ("batman-adv: tvlv - convert roaming adv packet to use tvlv unicast packets")
