Subject: [PATCH][next] ALSA: hda/hdmi: Replace zero-length array with

Zero-length arrays are deprecated and we are moving towards adopting
C99 flexible-array members, instead. So, replace zero-length array
declaration in union audio_infoframe with the new DECLARE_FLEX_ARRAY()
helper macro.

This helper allows for a flexible-array member in a union.
