warning C28282: Format Strings must be in preconditions

This warning indicates that a __drv_formatString annotation is found, which is not in a _Pre_ (__drv_in) annotation (function parameters are by default _Pre_). Check whether the annotation used in an explicit block with a _Post_ (__drv_out) annotation. If so, remove the annotation from any enclosing block that has put it in a _Post_ context.
