Re: [PATCH v4] i2c: i2c-qcom-geni: Parse Error correctly in i2c GSI mode

[Mukesh Kumar Savaliya]

Thanks Vinod and Andi !

It had time and also there was a comment to get sign off from DMA 
maintainers, we have had review and discussion on DMA part too.

Hi Vinod, Since this is already merged, do you have preference to revert 
OR making a new change if any BUG OR design issue ? I can also fix the 
changes you suggest and raise a new patch in case of any real bug OR 
design expectations.
