That can't be. It should give the "this > depends on another symbol [USB] that is modular". That's not how it works, the enclosed symbols depend now on V4L_USB_DRIVERS, which is a boolean and it can only have two states. It doesn't matter on what V4L_USB_DRIVERS depends only the final value matters. (BTW if check the dependency debug output in menuconfig/xconfig, you'll see which values are relevant in the calculation of a symbol value.) > >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.

Let me know so I can cook up a patch (hopefully > before 2.6.22) should they become tristate. Using bool is clearly a bug and I'd prefer if it removed the defaults as well. bye, Roman
