The host controller would tell the core to check for a card, exactly like it does at all other times. That's the natural alternative to having the MMC core assume that card detection was broken in low power states, so that the core needed to forcibly remove the cards before suspend, and reprobe during resume processing. Having the MMC core make such needless assumptions can cause problems for the upper layers, including filesystems. - Dave _______________________________________________ linux-pm mailing list linux-pm@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/linux-pm
