From e08de99abe4f3da8df01fa478a23b96c04b1001c Mon Sep 17 00:00:00 2001 From: Pan Nengyuan Date: Tue, 25 Feb 2020 15:55:54 +0800 Subject: [PATCH] virtio-crypto: do delete ctrl_vq in virtio_crypto_device_unrealize Similar to other virtio-deivces, ctrl_vq forgot to delete in virtio_crypto_device_unrealize, this patch fix it. This device has aleardy maintained vq pointers. Thus, we use the new virtio_delete_queue function directly to do the cleanup.
