Subject: s390x: simplify virtio_ccw_reset_virtio
X-Git-Tag: v7.1.0~109^2~10
X-Git-Url: https://git.proxmox.com/?a=commitdiff_plain;h=997340f3c5190a311902eeaabd9413434e97ff4c;p=mirror_qemu.git

s390x: simplify virtio_ccw_reset_virtio

Call virtio_bus_reset instead of virtio_reset, so that the function
need not receive the VirtIODevice.
