Since the initial code merged in 2012, the last case of the switch
has a useless test on 'retval' that is not assigned in the case.
Since 'retval' is initialized to ERROR_OK, the condition is always
false.
Drop the check on 'retval'.
While there, drop the useless parenthesis around the 'case' and
add the 'break' statement.
