Subject: [PATCH] ALSA: hda/hdmi: Replace zero-length array with DECLARE_FLEX_ARRAY() helper
Git-commit: 999b95a72d90ed7a7073eae594fa35462d71854f
Patch-mainline: v6.1-rc1
References: jsc#PED-850
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.
