It's exactly the same as Dinghao's patch: https://lore.kernel.org/linux-samsung-soc/20200522011659.26727-1-dinghao.liu@xxxxxxxxxx/ which you reviewed. It has even the same commit msg (although it's difficult to be creative here). I think it's better to resend his patch instead. Best regards, Krzysztof
