Subject: RE: [v12, 0/8] Fix eSDHC host version register bug
+ Greg
Hi Greg,
I submitted this patchset for a MMC bug fix, and introduce the below patch which needs your ACK.

https://patchwork.kernel.org/patch/9342913/
Could you help to review it and give some comments or ACK.
Thank you very much.
Best regards,
Yangbo Lu
