She genuinely wrote that code, so I wanted to give her credit, but I see how it's odd to kind of fix up the original patch in the same series. I am now leaning towards merging this patch into 2/8, and also the SMC access lock (7/8), since it's not really safe without them. But then still keep Vedashree's ACPI patch (4/8) separate, as well as the DT patch, and the auto-activate, since they are somewhat optional. If you have better ideas, I am all ears. Cheers, Andre
