Will send updated patch set in a few. You and Subhash are on the Cc.
Once again, the Auto-CMD23 is completely untested. I would be
extremely grateful if you can verify it.
Is there any kind of error injection mechanism you guys use to verify
the error paths for Auto 12/23?

By the way -

+       /* If the host can perform ADMA operation, we reset SDMA flag */
+       if (host->flags & SDHCI_USE_ADMA)
+               host->flags &= ~SDHCI_USE_SDMA;

This seems completely unnecessary, as the code already prefers ADMA to
SDMA. What do you think?
