> Fix PTP pins verification not to contain tainted arguments. As a new PTP pins configuration is provided by a user, it may contain tainted arguments that are out of bounds for the list of possible values that can lead to a potential security threat. Change pin's state name from 'invalid'
to 'empty' for more clarification.
