Message-ID: <YzIdiQLXup1qtf6l@work> Date: Mon, 26 Sep 2022 16:45:45 -0500 From: "Gustavo A. R. Silva" <gustavoars@...nel.org> To: Herbert Xu <herbert@...dor.apana.org.au>, "David S. Miller" <davem@...emloft.net> Cc: linux-crypto@...r.kernel.org, linux-kernel@...r.kernel.org, "Gustavo A. R. Silva" <gustavoars@...nel.org>, linux-hardening@...r.kernel.org Subject: [PATCH][next] crypto: talitos - Replace zero-length arrays 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 arrays declarations in anonymous union with the new DECLARE_FLEX_ARRAY() helper macro. This helper allows for flexible-array members in unions.
