From 999b95a72d90ed7a7073eae594fa35462d71854f Mon Sep 17 00:00:00 2001 From: "Gustavo A. R. Silva" Date: Mon, 29 Aug 2022 16:52:03 -0500 Subject: [PATCH] ALSA: hda/hdmi: Replace zero-length array with DECLARE_FLEX_ARRAY() helper 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.
