Vincent Whitchurch 26391e49d5 mmc: dw_mmc: Only inject fault before done/error ... The fault injection function can set EVENT_DATA_ERROR but skip the setting of ->data_status to an error status if it hits just after a data over interrupt. This confuses the tasklet which can later end up triggering the WARN_ON(host->cmd || ..) in dw_mci_request_end() since dw_mci_data_complete() would return success. Prevent the fault injection function from doing this since this is not a real case, and ensure that the fault injection doesn't race with a real error either.
