    mmc: core: Enable tuning according to the actual timing · e10c3219
    Carlo Caione authored
    While in sdhci_execute_tuning() the choice whether or not to enable the
    tuning is done on the actual timing, in the mmc_sdio_init_uhs_card() the
    check is done on the capability of the card.
    
    This difference is causing some issues with some SDIO cards in DDR50
    mode where the CDM19 is wrongly issued.
    
    With this patch we modify the check in both
    mmc_(sd|sdio)_init_uhs_card() functions to take the proper decision
    only according to the actual timing specification.
