Now, you'd have to formalise the submission - add your Signed-off-by line, provide a suitable patch description. More importantly, it certainly has to be updated for 2.6.32 and 2.6.33 - the biggest change since 2.6.31 has been the conversion to the v4l2-subdev API, and a smaller one - the addition of the mediabus API. For a single driver these are not very big changes, I could help you with them, but you certainly would have to re-test your setup with the current kernel. Would you be able to do that? And then, of course, we'd also have to pass your driver through the usual review rounds.
