Subject: vhost vdpa: fix vhost_vdpa_open error handling
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=37787e9f81e2e586b526ff5c29c94e4f41513e80;p=linux.git

vhost vdpa: fix vhost_vdpa_open error handling

We must free the vqs array in the open failure path, because
vhost_vdpa_release will not be called.
