Each function has a different data type for max_segments,
Modify to match unsigned short(host->max_segs).
* unsigned short max_segs; /* see blk_queue_max_segments */
1) Return type : unsigned int
static unsigned int mmc_get_max_segments(struct mmc_host *host)
{
return host->can_dma_map_merge ? MMC_DMA_MAP_MERGE_SEGMENTS :
host->max_segs;
}
2) Parameter type : int
mmc_alloc_sg(mmc_get_max_segments(host), gfp);
-> static struct scatterlist *mmc_alloc_sg(int sg_len, gfp_t gfp)
3) Parameter type : unsigned short
blk_queue_max_segments(mq->queue, mmc_get_max_segments(host));
-> void blk_queue_max_segments(struct request_queue *q,
unsigned short max_segments)

I am not sure whether it is mandatory necessary here, but it is OK for me.
