[PATCH 0/2] mmc: rtsx: add check before sending request

[micky_ching]

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.
