But i'm not sure, happen for all sdhci-controller. so i send to RFC patch.. I also hope apply my code unconditionally. the reason using quirk...every card didn't happen this issue.. if not happen this issue, we need not set timeout value..at that time.. when needs, entered and set timeout value..(conditionally) >> Card is configurable with eMMC spec..But sdhci-controller didn't >> support that card.
