-Subject: [PATCH] mmc: sunxi: Don't start commands while the card is busy
-
-Some sdio wifi modules have not been working reliable with the sunxi-mmc
-host code. This turns out to be caused by it starting new commands while
-the card signals that it is still busy processing a previous command.
-
-This commit fixes this, thereby fixing the wifi reliability issues on
-the Cubietruck and other sunxi boards using sdio wifi.
