[PATCH v5 16/20] vfio/ccw: Make vfio cdev pre-openable by passing a file handle

This gives management tools like libvirt a chance to open the vfio cdev with privilege and pass FD to qemu. This way qemu never needs to have privilege to open a VFIO or iommu cdev node. Signed-off-by: Zhenzhong Duan --- hw/vfio/ccw.c | 34 +++--- 1 file changed, 31 i
