Subject: [PATCH 4.14 24/38] Bluetooth: 6LoWPAN: add missing hci_dev_put() in get_l2cap_conn()
Date: Mon, 12 Dec 2022 14:19:25 +0100 [thread overview]
Message-ID: <20221212130913.316286334@linuxfoundation.org> (raw)
In-Reply-To: <20221212130912.069170932@linuxfoundation.org>
From: Wang ShaoBo <bobo.shaobowang@huawei.com>
[ Upstream commit 747da1308bdd5021409974f9180f0d8ece53d142 ]
hci_get_route() takes reference, we should use hci_dev_put() to release
it when not need anymore.
Fixes: 6b8d4a6a0314 ("Bluetooth: 6LoWPAN: Use connected oriented channel instead of fixed one")
