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.
