Your best bet it to clone Linus' git tree and then apply your patches:

1. clone Linus' git tree:
    git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
2.    a) apply your first patch
       b)  if you patch adds new files to the source tree, add them:
            git add path/to/files/file.c
            git add path/to/files/file.h
            etc.  if the patch only modifies patches that are already
in the tree, you do not need to add them.
       c) when the patch is applied commit it:
           git commit -a -s
       d) when you run the commit command you will be prompted to
enter a commit message.  The commit message has the following format:

subsystem: patch description

description of what the patch does.

Signed-off-by: Your name <your_email at domain.com>

E.g.,

fb: add initial code for video 5000 graphics

This adds the initial support for the video 5000
graphics adapter.  It supports vga and lcd connectors.

Signed-off-by: Joe Developer <joe.developer at example.com>

    e) repeat steps a-d for all of your patches
3. generate patches:
git format-patch -n

where n is the number of patches you committed.  E.g., if your driver
consists of 5 patches:
git format-patch -5

4. Send the patches to the list.

We really want to know the way to submit a kernel driver to kernel.org. I have received a document file which is on http://kernel.org/doc/Documentation/SubmittingDrivers, but I still cannot find out a place to where our drivers should be uploaded. The document say ¡°please submit it to the maintainer listed in MAINTAINERS in the kernel file.¡±So where can I find the maintainer and what to do next. Would you please help me. Thank you so much.
