comparison-negation

Flag a negated comparison — !(a == b), !x < y — which reads more clearly as the opposite comparison (a != b, x >= y).

The fix is withheld when a comment in the operand would otherwise be lost.

Negating an equality test:

if (!(a == b)) stop()

  |     ^^^^^^^^^ negated comparison is clearer as the opposite operator
  = help: Flip the comparison instead of negating it.

After applying the fix:

if (a != b) stop()
