Cover letter [PATCH 0/2] mmc: rtsx: add check before sending request
From: Micky Ching <[email protected]>
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.
