What coding style should I use?

If you are working on a new piece of code, you should follow the coding style from the file Documentation/CodingStyle in your kernel source directory.

When working on an existing piece of code, follow the coding style from that code. After you edit a file, a reader should not be able to tell just from coding style which parts you worked on.

What do I do if my patch got rejected due to the coding style?

The patch may well come back in the "sorry" category rather than the "applied" category, with suggestions on what should be changed to make it better and a request to resubmit it. This doesn't mean you should give up. It means you did a good job and the maintainers think it's worth trying to get you to make the job even better. Remember: you can't polish a turd.
