At present if reading a BAR returns 0xffffffff (e.g. the device is not present) then the value is masked and a different value is returned. This makes it harder to detect the problem when debugging.

If you insisting on the code, you may need to reword the commit message, at least by removing ambiguous "device not present", because this is not how PCI spec defines situations when device is not present.
