The infield fly rule doesn't apply to line drives or a bunted ball. There's an additional rule that applies to an intentionally dropped ball including line drives and fly balls when the infield fly rule is not called. This rule states that the batter is out if a defensive player intentionally drops the ball with the intention of gaining a defensive advantage by not catching it. An example is there's a runner on first and a line drive is hit to the shortstop close to second base. The shortstop drops the ball in order to try and turn a double play. This rule differs from the infield fly rule in a number of ways:

This rule can apply with a runner on first base or first and third in addition to the force plays listed for the infield fly rule
This rule can be called by the umpire after the play occurs. An infield fly rule must be called when the ball is in the air.
Once the umpire has made the call, the ball is dead and the base runners must return to their original bases. They cannot advance on the play.
