Hi, We got your patch from stable. On p2020 we had mmc issues, and bisected the issue to your patch. Both prior patches seems to modify quirks2. Fixes: 05cb6b2a66fa ("mmc: sdhci-of-esdhc: add erratum eSDHC-A001 and A-008358 support") Fixes: a46e42712596 ("mmc: sdhci-of-esdhc: add erratum eSDHC5 support") So I'm not sure if your changes were done correctly. Daniel
