No, I just try to understand the process. I don't fully understand what 
is the role of independent developer in the process of submitting new 
drivers to LK. What I mean is - hardware device vendors always ship 
device driver with their products. In this case several options are 
available:
1.) HW vendor ships only closed-source drivers and is not interested to 
open source this work.
2.) HW vendor publishes device drivers to the community by himself
3.) HW vendor put the device driver sources to their website ready for 
downloading and building, but make no effort for integrating them to LK.

Actually, I see that in this plot independent developer could only 
participate in case 3 - i.e. take the published sources, fix coding 
style, satisfy other community needs and integrate this driver to LK 
(By the way is this a real case? Or drivers aren't integrated in such 
way?). I see no other ways how independent person could participate. Am 
I wrong?
