This patch added mmc_power_off after mmc_attach_sd()
i found that didn't detect the second card insert.(using SDHCI)
you can see the below log.
i want to know that somebody know this issue...
->first card inserted (correct card detect)
# mmc1: new SDHC card at address e624
mmcblk1: mmc1:e624 SU04G 3.69 GiB
mmcblk1: p1
#
# mmc1: card e624 removed
-> second card inserted
mmc1: error -110 whilst initialising SD card
mmc1: Card removed during transfer!
mmc1: Resetting controller.
-> third card inserted
mmc1: new SDHC card at address e624
mmcblk1: mmc1:e624 SU04G 3.69 GiB
mmcblk1: p1
I added mmc_power_off() after only mmc_attach_sd().
