Subject: [PATCH v2 1/2] Bluetooth: ISO: Fix not releasing hdev reference on iso_conn_big_sync
Date: Mon, 1 Jun 2026 16:41:56 -0400 [thread overview]
Message-ID: <20260601204157.13923-1-luiz.dentz@gmail.com> (raw)
From: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>
hci_get_route() returns a reference-counted hci_dev pointer via
hci_dev_hold(). The function exits normally or with an error without ever
releasing it.
Fixes: 07a9342b94a9 ("Bluetooth: ISO: Send BIG Create Sync via hci_sync")
Reported-by: Sashiko <sashiko-bot@kernel.org>
Signed-off-by: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>
