You should also send it to linux-fbdev (CCed) so interested people have
a better chance of seeing it (and quoting previous mail below).

If you have a git tree with history it might be nice. Otherwise it's
easier to review if you can split the big-patch into multiple incremental
parts adding some functionality each (that incremental nature would also
be expected from a git tree).

Your tree at https://github.com/logicbricks/linux_kernel looks weird,
you seem to have imported just the subfolders of kernel tree you worked
on instead of cloning e.g. v3.8 release and applying your driver on top
of it. This way it's not possible to merge your tree and it's rather hard
to find out what belongs to your driver or not.
