Takashi,
This fix should be confirming to the HDA spec, and works together with the DRM part of the ELD patch.
The HDA spec does not mention that Monitor_Name_String is an '\0' ending string, and it allows NML to be 1, which is only valid when MNL does not count the possible ending '\0'.
Thanks, Fengguang

I noticed that the last character of the ELD monitor name is lost, this fixes the issue.
