Subject: drm/radeon: Use correct value for unknown audio/video latency
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Valid values are 1 to 251 for 0 to 500 ms latency, 0 for unknown
and 255 for audio/video unsupported by sink, according to HDMI 1.3 spec.
Also matches Radeon HDA verb 0xf7b documentation.
