From 1b808d5be070e9d07e5d0e5b825a31a0cf87001d Mon Sep 17 00:00:00 2001 From: Eric Auger Date: Mon, 17 Oct 2016 10:57:59 -0600 Subject: vfio: Pass an error object to vfio_get_group Pass an error object to prepare for migration to VFIO-PCI realize. For the time being let's just simply report the error in vfio platform's vfio_base_device_init(). A subsequent patch will duly propagate the error up to vfio_platform_realize.
