You need to at least the following steps:

1. Add your module to an appropriate location in the source tree, e.g.
drivers/net/ or drivers/char/, or whereever it fits best depending on
what it does.

2. Edit the Makefile in that directory so your driver gets built, e.g.
by adding a line 'obj-m += your-driver.o'.

The optional but recommended steps are:

3. Add the driver to an appropriate Kconfig file, typically in the same
directory as your driver, and change your Makefile to 
use 'obj-$(CONFIG_YOUR_DRIVER) += your-driver.o'.

4. Learn to use 'quilt', or a similar tool, to manage your patch against
the kernel.

5. If you ask questions on the mailing list, make sure everyone has access
to your patch, e.g. by uploading it to a web site.
