Trey Ramsay 8fee476b21 mmc: core: Fix some driver hangs when dealing with broken devices ... There are infinite loops in the mmc code that can be caused by bad hardware. The code will loop forever if the device never comes back from program mode, R1_STATE_PRG, and it is not ready for data, R1_READY_FOR_DATA. A long timeout is added to prevent the code from looping forever. The timeout will occur if the device never comes back from program state or the device never becomes ready for data. It's not clear whether the timeout will do more than log a pr_err() and then start a fresh hang all over again. We may need to extend this patch later to perform some kind of reset of the device (is that possible?) or rejection of new I/O to the device.
