ASoC: uapi: Replace zero-length arrays with __DECLARE_FLEX_ARRAY() he…
72f44f1 
…lper

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

This helper allows for flexible-array members in unions.
