From 0752bb32aed2c5dd85821195a507a1079c4835f7 Mon Sep 17 00:00:00 2001 From: Mika Westerberg Date: Thu, 22 Jun 2023 14:59:12 +0300 Subject: [PATCH] thunderbolt: Fix memory leak in tb_handle_dp_bandwidth_request() 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.
