Finally I got this microSD to SD adapter to test the ATP card on RK3288
platform too. As expected, card fails without the patch:

 $ dd if=/dev/urandom of=./test bs=1M count=10

does freeze system without any response

So I can verify failing CMD23 behaviour on imx6 and rk3288 running
kernel 4.14. Applying the patch does fix the issue on both platforms.

Could you queue up this patch now?

Thanks
