Old driver sample code does not return an EFI_UNSUPPORTED status code if a callback occurs for something which is unrecognized.
Now any call back type except:EFI_BROWSER_ACTION_FORM_OPEN, EFI_BROWSER_ACTION_FORM_CLOSE, EFI_BROWSER_ACTION_FROM_RETRIEVE and EFI_BROWSER_ACTION_FORM_CHANGING, all return EFI_UNSUPPORTED. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@11518 6f19259b-4bc3-4df7-8a09-765794883524
