Jason Wang (6):
mdev: class id support
modpost: add support for mdev class id
mdev: introduce device specific ops
mdev: introduce virtio
.
So this patch adds id_table to mdev_driver and class_id for mdev
device with the match method for mdev bus.

driver.

mdev based config ops. This means it is a software transport between
mdev driver and mdev device. The transport was implemented through
device specific ops which is a part of mdev_parent_ops now.
