So, DVB won't break without V4L. So, if you have only DVB_CORE = 'M', MEDIA_TUNER = 'M'. This patch (together with another patch) is needed to fix a bug reported by Alistair, at LKML. In fact, this will fix some issues that happens if DVB_CORE is 'Y' and VIDEO_DEV is 'M' (or the reverse), since, on those cases, all tuner drivers should be 'Y'. Also, it should be noticed that _all_ tuners that can be shared between DVB and V4L need to support I2C, since this is a requirement for tuner-core to work. What this patch does is to replace DVB_CORE || VIDEO_DEV to VIDEO_MEDIA, and to replace: (DVB_CORE || VIDEO_DEV) && I2C (that is common to all tuners under common/tuners) to: MEDIA_TUNER. What happens is that our Kconfig stuff is so complex that even small changes are breaking the Kbuild. We really need to make things simpler, otherwise we will keep breaking it on every new kernel.
