Luca, can you resend without Rob's Review tag and ask him to pick it up? Best regards, Krzysztof

This means (as far as I understand) that neither can really properly apply this (rebased) patch as one tree will have missed the other commit. Does it make sense to send a v3 rebased on linux-next now, or wait until this has settled down in torvalds's tree? Regards Luca > > Best regards, > Krzysztof

Conflicts can be resolved, you just need to choose one tree to based on. Best regards, Krzysztof

Yeah of course, but currently sm6350 and sm8150 patches are lined up to be merged in the next merge window from different trees which just make it difficult. > > > tree, but there was also a sm8150 patch applied through Linus Walleij's > > tree.

I mean either this conversion patch includes sm8150 or it doesn't but given it's applied to some tree and lined up for the next merge window it should probably include it? > > > > > Does it make sense to send a v3 rebased on linux-next now, or wait until > > this has settled down in torvalds's tree? > > Conflicts can be resolved, you just need to choose one tree to based on. If conflict resolution will be done when merging Linus' and Rob's tree (e.g. add sm8150 to the yaml) then this v2 can be applied to Rob's tree now. Otherwise, I'll just wait until everything's merged into torvald's tree so the issue disappears. Regards Luca > > > Best regards, > Krzysztof
