Subject: [PATCH v2] vhost-vdpa: Fix the wrong input in config_cb
Date:   Wed, 29 Sep 2021 17:09:33 +0800

Fix the wrong input in for config_cb. In function vhost_vdpa_config_cb,
the input cb.private was used as struct vhost_vdpa, so the input was
wrong here, fix this issue

Fixes: 776f395004d8 ("vhost_vdpa: Support config interrupt in vdpa")
