From ae03c3771b8cbbed3802ad1153d896c32015c520 Mon Sep 17 00:00:00 2001 From: Max Gurtovoy Date: Thu, 5 Aug 2021 22:18:59 -0300 Subject: vfio: Introduce a vfio_uninit_group_dev() API call This pairs with vfio_init_group_dev() and allows undoing any state that is stored in the vfio_device unrelated to registration. Add appropriately placed calls to all the drivers. The following patch will use this to add pre-registration state for the device set.
