Those & should be |
/* If no card caps specified then assume them all */
if (!((mmc->caps & MMC_CAP_SD) ||
(mmc->caps & MMC_CAP_MMC) ||
(mmc->caps & MMC_CAP_SDIO)))
mmc->caps |= MMC_CAP_SD | MMC_CAP_MMC | MMC_CAP_SDIO;
or more compactly,

/* If no card caps specified then assume them all */
if (!(mmc->caps & (MMC_CAP_SD | MMC_CAP_SDIO | MMC_CAP_MMC)))
mmc->caps |= MMC_CAP_SD | MMC_CAP_MMC | MMC_CAP_SDIO;
