From: Micky Ching <micky_ching@xxxxxxxxxxxxxx> Add check before sending request can make request return faster. - finish request if no card exist This can make request finish faster, especial for some sdio card, when card removed, there still a lot of command pending, if we check card exist and stop request, the card will disappear faster in user space. - check sg_count before long data xfer modify sg_count type unsigned -> int, because dma_map_sg() return int, and this value can be negative to indicate some error occurs.
