Hello Ashok,

A few days ago I wrote a lengthy answer to the same question in quora, if
you want to take a look:
www.quora.com/Linux/Whats-the-best-way-to-learn-device-driver-development-on-Linux

Short answer:

If you have an Android device, there is a big probability that the drivers
for that hardware have not yet been pushed upstream. Android and Linux
differ slightly but enough to force a developer to choose to write a driver
either for Android or Linux.

So, a useful contribution and an excellent learning process could be porting
Android device drivers to Linux.
