From: Ranbir Singh <Ranbir.Singh3@Dell.com>
The function UpdatePciInfo has switch-case code in which there are fall
through from case 32: to case 64:. While this is seeemingly intentional,
it is not evident to any general code reader why there is no break; in
between. Adding
// No break; here as this is an intentional fallthrough.
as comment in between makes it explicit. Incidentally, the comment
satisfies Coverity as well.
