Merge tag 'asoc-hdmi-codec-pdata' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into drm-next

ASoC: Add private data for HDMI CODEC callbacks

Allow the HDMI CODECs to get private data passed in in callbacks.

[airlied:
Add STI/mediatek patches from Arnd for drivers merged later in drm tree.]
