Done:
if (EFI_ERROR (Status)) {
if (PciIo != NULL && Enabled) {
PciIo->Attributes (
PciIo,
EfiPciIoAttributeOperationSet,
OriginalAttributes,
NULL
);
}
}
In above codes, VS2012/VS2010 will report that "OriginalAttributes"
will be used without initialization. But in fact, when the if expression
is true(if (PciIo != NULL && Enabled)), the "OriginalAttributes" must be
initialized. In order to fix this false positive issue, we initialize the
"OriginalAttributes" after declaration.
