From: Ranbir Singh <[email protected]>
The function SubmitResources has a switch-case code in which the
case ACPI_ADDRESS_SPACE_TYPE_MEM: which falls through to
case ACPI_ADDRESS_SPACE_TYPE_IO: if there is no scenario of
return EFI_INVALID_PARAMETER;
While this may be intentional, it is not evident to any general code
reader as well as any static analyzer tool. Just adding
// No break; here as this is an intentional fallthrough.
as comment in between makes any reader as well as Coverity happy.
