Thanks for your review. I am working on v2 at
https://github.com/ribalda/linux/tree/serdev2 it fixes your comments except
the line cut for DEVICE_ATTR, I want also to make checkpatch happy ;)

Will send v2  to the list after I got more feedback, you can of course ping
me if there is something in my tree that it is not fixed properly.

Cheers
