I think that code is from the original NXP driver and appears to be used to support multiple slots attached to the same block (so you can be asked to process a request for slot A while the block is busy processing an earlier request for slot B). I don't have any hardware setup like this, everything I have has only a single slot so I don't believe I have ever seen that branch of the conditional execute. -- To unsubscribe from this list: send the line "unsubscribe linux-mmc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
