Do you mean that the input events cannot be used with kernel < 2.6.19, while CONFIG_INPUT can be set? Anyway, this patch seems complex. It would have been easier to simply unset CONFIG_INPUT when kernel < 2.6.19. I join the diff of gspca.c between v4l-dvb and my repository. This last one is closer to the git version and there are still other changes done in git. How do you think I should merge?
