You may wish to get a copy of 'Linux Device Drivers, 3rd Edition' and read it before posting lots of questions here.
A free version is available online, and last I checked it was the very first hit if you google for 'Linux device drivers".
This! Please read LDD, LKD and ULK fully before asking questions.
