Date: Mon, 29 Aug 2022 16:52:03 -0500 From: "Gustavo A. R. Silva" <gustavoars@...nel.org> To: Jaroslav Kysela <perex@...ex.cz>, Takashi Iwai <tiwai@...e.com> Cc: alsa-devel@...a-project.org, linux-kernel@...r.kernel.org, "Gustavo A. R. Silva" <gustavoars@...nel.org>, linux-hardening@...r.kernel.org Subject: [PATCH][next] 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.
