Both options are defined identical: config {BCMA_POSSIBLE,SSB_POSSIBLE} bool depends on HAS_IOMEM && HAS_DMA default y While this kind of duplication might still be acceptable in order to have both sections work independently of each other, it really gets strange when looking how they are then used in expression where both of those configs appear. E.g., config B43's dependency is: (BCMA_POSSIBLE || SSB_POSSIBLE) && MAC80211 && HAS_DMA Note that BCMA_POSSIBLE and SSB_POSSIBLE identical and already have HAS_DMA as condition, so that is then also another duplication. Another example is the choice Supported bus types in B43, which already depends on B43 and hence, we know that HAS_IOMEM && HAS_DMA holds, so all stated dependencies in the choice are true in all cases. Given this whole confusion around the use of these two symbols, just remove them and replace them with the expression they intend to abbreviate.
