[PATCH 2/2] mmc: block: add CMD13 polling for ioctl() cmd with R1B response

currently there is no CMD13 polling and other code to wait card change to transfer state after R1B command completed. and this polling operation cannot do in user space, because other request may coming before the CMD13 from user space. Signed-off-by: Chaotian Jing --- drivers/mmc/core/block.c |
