Give a name to unnamed parameters thus addressing violations of MISRA C:2012 Rule 8.2 ("Function types shall be in prototype form with named parameters"). Keep consistency between parameter names and types used in function declarations and the ones used in the corresponding function definitions, thus addressing violations of MISRA C:2012 Rule 8.3 ("All declarations of an object or function shall use the same names and type qualifiers"). No functional changes.
