Subject: Re: [PATCH] tty: fill console_driver->driver_name

Thank greg k-h.
1. I guess nothing is going to break with this change, I'm not sure about that
2. why does it need to be changed?
    "unknown" confuse us a little, and we want to know the reason: bug
or some else.
    In fact, it is a known tty driver.
3. finally, I also consider this patch is trivial, but I just expect
"cat /proc/tty/drivers" to be better.

thanks,
Cheng
