It means runtime PM is disabled for your device. Which doesn't make sense, assuming you had MMC_CAP_POWER_OFF_CARD configured (if you didn't, you wouldn't end up calling runtime PM api at all). If you post your entire diff, I might be able to spot what's wrong. As a side note, if the additional CMD5 arg=0 fixes both sd8686's and b43's issues, we might consider removing MMC_CAP_POWER_OFF_CARD entirely. But let's not rush with that yet. -- To unsubscribe from this list: send the line "unsubscribe linux-mmc" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
