Hi Jaehoon, For "mmc: core: prepare the next version of eMMC card" you may have my ack! But not for "mmc: core: add the quirk for broken revision". The reason is simply that it is not needed right now and we don't know if it ever will be. So I suggest to skip this for now and we can get back to this later.
