V4L_USB_DRIVERS=y turns USB into =y? That can't be. It should give the "this depends on another symbol [USB] that is modular". >I'm also a little irritated by the "default y", if I enable V4L I'm very >tempted to check what other useless stuff has been automatically enabled, >which I have to turn off again. The default y only applies to the "menu" folders, not actual code. There have been discussions to remove the default-ys again, I've sent a patch [http://lkml.org/lkml/2007/5/12/216], but nothing happened. So, should all affected menuconfigs be transformed into tristates, what do you think, Roman? Let me know so I can cook up a patch (hopefully before 2.6.22) should they become tristate.
