readability-static-accessed-through-instance

Checks for member expressions that access static members through instances, and replaces them with uses of the appropriate qualified-id.

Example:

The following code:

struct C {
  static void foo();
  static int x;
};

C *c1 = new C();
c1->foo();
c1->x;

is changed to:

C *c1 = new C();
C::foo();
C::x;
