The check finds function parameters of a pointer type that could be changed to
point to a constant type instead.
-When const is used properly, many mistakes can be avoided. Advantages when using
-const properly:
- * prevent unintentional modification of data
- * get additional warnings such as using uninitialized data
- * make it easier for developers to see possible side effects

This check is not strict about constness, it only warns when the constness will
make the function interface safer.

// warning here; the declaration "const char *p" would make the function
// interface safer.
int f3(struct S *p) {
*(p->a) = 0;
