Thanks for posting the fix to Mainline

imho this should contain a fixes-Tag as it fixes eMMC-Access on mt7622/Bpi=
-R64

before we got these Errors on mounting eMMC ion R64:

[   48.664925] blk_update_request: I/O error, dev mmcblk0, sector 204800 o=
p 0x1:(WRITE) flags 0x800 phys_seg 1 prio class 0
[   48.676019] Buffer I/O error on dev mmcblk0p1, logical block 0, lost sy=
nc page write

Fixes: 966580ad236e ("mmc: mediatek: add support for MT7622 SoC")
Tested-By: Frank Wunderlich <frank-w@public-files.de>

and it needs to be fixed at least for 5.4+, so adding stable-CC
