Subject: [PATCH] scsi: qedf: fix a memleak in qedf_alloc_global_queues
Date: Wed, 27 Dec 2023 13:42:55 +0800
Message-Id: <20231227054255.28583-1-dinghao.liu@zju.edu.cn>
Precedence: bulk

When qedf_alloc_bdq() fails, qedf->global_queues should
be freed to prevent potential memleak. It's the same for
the following error handling paths.

Fixes: 61d8658b4a43 ("scsi: qedf: Add QLogic FastLinQ offload FCoE driver framework.")
