/usr/src/sys/arm/broadcom/bcm2835/bcm2835_sdhci.c:721:26: error: unused variable 'sc' [-Werror,-Wunused-variable]
        struct bcm_sdhci_softc *sc = device_get_softc(slot->bus);
                                ^
1 error generated.

This is because the sc is only used in:

        KASSERT(sc->dmamap_seg_count == 0,
            ("data pending interrupt pushed through SDHCI framework"));

and this was a non-debug build: so the KASSERT did not use sc either.
