I don't think you did: I asked you specifically to add code to interact with
the existing in-kernel interfaces to use the functionality provided by the
device. Pick any (at least two) subsystems and add support, but leave
out any custom user space interfaces (miscdevice, debugfs, sysfs, ...)
for the moment.
