The reset device operation, usually is an operation that might fail from
various reasons. For example, the controller might be in a bad state and
can't answer to any request. Usually, the paravirt SW based virtio
devices always succeed in reset operation but this is not the case for
HW based virtio devices.
This commit is also a preparation for adding a timeout mechanism for
resetting virtio devices.

You missed drivers/s390/virtio/virtio_ccw.c.
virtio_ccw_reset() should probably return -ENOMEM on allocation failure
and forward the return code of ccw_io_helper().
thanks, I found another 1-2 places that I missed. I'll update in v2.
