Which kernel version introduced the regression?

Do we not need mpt-fix-enable-lsi-sas-to-use-msi-as-default.patch as
well, to fix this regression?

I sent mpt-fix-enable-lsi-sas-to-use-msi-as-default.patch to the
maintainers a week ago and it was ignored, along with everything else. 
If this happens again I shall merge it under my own cognisance, along
with everything else.
