In sdhci_add_host()
We have the following
...
mmc->caps |= MMC_CAP_SDIO_IRQ | MMC_CAP_ERASE | MMC_CAP_CMD23;
if (host->quirks & SDHCI_QUIRK_MULTIBLOCK_READ_ACMD12)
host->flags |= SDHCI_AUTO_CMD12;
/* Auto-CMD23 stuff only works in ADMA or PIO. */
if ((host->version >= SDHCI_SPEC_300) &&
((host->flags & SDHCI_USE_ADMA) ||
!(host->flags & SDHCI_USE_SDMA))) {
host->flags |= SDHCI_AUTO_CMD23;
DBG("%s: Auto-CMD23 available\n", mmc_hostname(mmc));
} else {
DBG("%s: Auto-CMD23 unavailable\n", mmc_hostname(mmc));
}
...
I'm not clear what the difference is between mmc->caps & host->flags, but shouldn't we move setting MMC_CAP_CMD23 inside the 'Auto-CMD23' if check?
