I have posted the fixer here

https://reviews.llvm.org/D93182

It catches about 200 problems in 100 files, I'll be posting these soon.

clang-tidy-fix's big difference over checkpatch is using the __printf(x,y) attribute to find the log functions.

I will be doing a follow-on to add the missing __printf or __scanf's and rerunning the fixer.
