SDHI automatically sends CMD12 when the desired amount of data was transferred after multi block commands. However, the response from that CMD12 was never reported back to the mmc core, so that errors like ECC might go unnoticed. This series aims to fix that and clean up minor issues on the way when dealing with the autocmd12 feature. It is marked as RFC because, so far, I could only test that the success case was reported back to the MMC core. An error case (like ECC) could not be created yet. But people inside Renesas will try some SD tester soon, and I also will keep writing GB to an 64MB cards until wear level problems kick in (though, I have to admit, I am trying this for days now and my trust in lifetimes of SD cards has significantly increased since). I wanted to present the patches early in case other parties are interested in testing, too. The patches are based on mmc-next.
