The STOP command can terminate a data transfer between a memory card and mmc controller. As show in Synopsys DesignWare Cores Mobile Stroage Host Databook:

Data timeout and Data end-bit error will terminate further data transfer by mmc controller. So we should not send abort command to terminate a data transfer again if we got DRTO and EBE interrupt. After this patch, all mmc_test cases can pass on RK3288-Pink2 board. Signed-off-by: Addy Ke <redacted>
I did not run all the tests listed in /sys/kernel/debug/mmc*/*/testlist because some of them will overwrite the data in my card but at least the read ones completed successfully and $subject does not cause a regression in the Exynos5250 Snow, Exynos5420 Peach Pit and Exynos5800 Peach Pi Chromebooks where I tested it.
