In the sdhci_msm_execute_tuning(), we will send CMD13 only if host->card is present because it needs the card->rca as its argument to be sent. For emmc, host->card is already updated immediately after the mmc_alloc_card(). In the similar way, this change is for SD card. Without this change, tuning functionality will not be able to send CMD13 to make sure the card is ready for next data command. If the last tuning command failed and we did not send CMD13 to ensure card is in transfer state, the next read/write command will fail. Signed-off-by: Sahitya Tummala Signed-off-by: Bao D.
