[PATCH] mmc: queue: Match the data type of max_segments

[Chanwoo Lee <cw9316.lee@xxxxxxxxxxx>]

From: ChanWoo Lee <cw9316.lee@xxxxxxxxxxx>

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)
