To submit the m5602 webcam driver mainline (or not)

I'm currently torn between submitting the m5602 webcam upstream.
So far, the software has been maturing pretty nicely. Some applications still do not work with the libv4l combo, but this seems more to be some initial struggle and Hans de Goede (the libv4l developer) has been pretty busy filing bugs at various projects trying to gain support for the library.

There are still various issues remaining: One sensor is still unidentified, the s5k83a goes crazy in high-lighting environments, the mt9m111 is still to dark initially but all in all things start to work.

One hard issue is that quite often someone reports an issue directly to me or via one of the mailing list. As I query the submitter for information no response is ever received. This makes it impossible for me to actually fix the bug, most annoying.

Anyway, submitting the project upstream is a good idea to get more coverage for the software and the submission must be done eventually. I've also been investigating to option to port the project to use the gspca framework but I still don't like the structure of it.
