v2 vs v1:
base on Avri's comment, drop the ioctl_rpmb_card_status_poll()
the user space program may access eMMC by ioctl(), after the ioctl() was
completed, it should ensure that eMMC is in transfer state, or it will
cause other thread which access eMMC got timeout error, as it assume that
card was in transfer state.
this patch add CMD13 polling for R1B command to avoid this issue.
Chaotian Jing (2):
mmc: block: make the card_busy_detect() more generic
mmc: block: add CMD13 polling for ioctl() cmd with R1B response
