The vsscanf function uses implicit type casting to populate the long
long integers in union val from the obsolete functions simple_strtol()
and simple_strtoll(). However the new functions kstrtol() and kstrtoll()
expect a pointer to the correct type, so we must be explicit about which
type we are using.
