if statement with structure member and rule 10.1

[misra-c]

Rule 10.1 is concerned with underlying types of expressions but not with the form of those expressions. Therefore two expressions with an underlying type of unsigned int should be treated in the same manner regardless of whether, for example, one is an object (variable) and the other is a member of a structure.

This would be something to discuss with the supplier of the checking tool as it seems to be diagnosing Rule 10.1 violations when it should not be doing so.
