What exact relation are you looking for? A character driver shouldn't
ever care about this, it should be very simple code. Have you tried
using something like the misc interface instead, which handles almost
all of this logic for you?
Posting your code is a good way for others to help as well, otherwise
answering vague questions is very hard.
good luck!
