Summary: [[ https://bugs.llvm.org/show_bug.cgi?id=39224 | PR39224 ]] As discussed, we can't always do the transform automatically due to that array-to-pointer decay of C array. In order to detect whether we can do said transform, we'd need to be able to see all usages of said array, which is, i would say, rather impossible if e.g. it is in the header. Thus right now no fixit exists. Exceptions: `extern "C"` code.
