The function mmc_blk_issue_rw_rq() is hopelessly convoluted and need to be refactored to it can be understood by humans. In the process I found some weird magic return values passed around for no good reason. Things are more readable after this. This work is done towards the goal of breaking the function in two parts: one just submitting the requests and one checking the result and possibly resubmitting the command on error, so we can make the usual path (non-errorpath) smooth and quick, and be called directly when the driver completes a request. That in turn is a prerequisite for proper blk-mq integration with the MMC/SD stack. All that comes later.
