I found my check for audio capability within CEA extension might has some conflict with Adam's patch to add more detailed mode from CEA ext block. But I haven't found Adam's patch in next tree, so I just kept my current change.
This fixed incorrect probe for DP monitor's audio. Fengguang helped to test this set. We got correct DP sound on Eizo EV2333W, and HDMI audio also worked with no regression found.
Patch is against Chris's drm-intel-next branch.
thanks.
