Subject: thunderbolt: Fix memory leak in tb_handle_dp_bandwidth_request()
From: Mika Westerberg <mika.westerberg@xxxxxxxxxxxxxxx>
commit 596a5123cc782d458b057eb3837e66535cd0befa upstream.
The memory allocated in tb_queue_dp_bandwidth_request() needs to be
released once the request is handled to avoid leaking it.
Fixes: 6ce3563520be ("thunderbolt: Add support for DisplayPort bandwidth allocation mode")
