We recently started using Clang Tidy on the Blender source. We found a 
couple of false positives of the `readability-non-const-parameters` check. 
One of those is fixed by this patch.

  struct MyStruct {
    float *values;
  };
  
  void myfunc(float *values) {
    MyStruct mystruct = {values};
  }

Without this patch, Clang Tidy reports that the `values` parameter of
`myfunc` can be const. It does not recognize that it is assigned to
a non-const data member of `MyStruct`.

Note, this is the first time I'm working with the LLVM source code.
So please let me know if I'm doing something wrong.
