Subject[PATCH 1/2] mmc: core: use card pointer as the first parameter of execute_tuning()
Date
We need to take the card pointer in execute_tuning() for mmc_send_status(),
but mmc->card is NULL in tuning state. So we need change the first parameter
of execute_tuning() to card pointer(struct mmc_card * card).
