The void (*pre_req) callback in the struct mmc_host_ops vtable is passing an argument "is_first_req" indicating whether this is the first request or not. None of the in-kernel users use this parameter: instead, since they all just do variants of dma_map* they use the DMA cookie to indicate whether a pre* callback has already been done for a request when they decide how to handle it. Delete the parameter from the callback and all users, as it is just pointless cruft.
