Well it's 100% the same diff so reviewing it separately doesn't really
make sense IMHO. When I do "msm8916/39" patches these are generally the
changes where strictly speaking there is no need to duplicate at all.
It could go into a common include between both. We just haven't found
a good solution/agreement yet how sharing SoC components could work.
