> FmpDeviceCheckImageWithStatus() handling
>
> From: Michael Kubacki <michael.kubacki at microsoft.com>
>
> Update the logic handling last attempt status codes from
> FmpDeviceCheckImageWithStatus() implementations to account for cases
> when the function return status code is EFI_SUCCESS (since the image was
> checked successfully) but the ImageUpdatable value is not valid.
>
> In addition the following sentence is removed from the LastAttemptStatus
> parameter definition for
> FmpDeviceCheckImageWithStatus() since it can lead to confusion.
> The expected status code value range is sufficient to implement the library
> API.
>
> "This value will only be checked when this
> function returns an error."
