Antwort: [PATCH v2 10/39] pci: Adjust dm_pci_read_bar32() to return errors correctly

-----"Simon Glass" sjg@chromium.org schrieb: -----

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.

Update the function to avoid masking in this case.
