From d6d8bb92fdde6390037bf9da174ed3ab551c04d7 Mon Sep 17 00:00:00 2001 From: Stefano Garzarella Date: Mon, 15 Mar 2021 17:34:45 +0100 Subject: vhost/vdpa: use get_config_size callback in vhost_vdpa_config_validate() Let's use the new 'get_config_size()' callback available instead of using the 'virtio_id' to get the size of the device config space.
