    Subject[PATCH 5.14 114/151] vhost-vdpa: Fix the wrong input in config_cb
    Date
    From: Cindy Lu <lulu@redhat.com>

    commit bcef9356fc2e1302daf373c83c826aa27954d128 upstream.

    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")
