From 56df3d408a8fa079bf4122895d6e004659795d4f Mon Sep 17 00:00:00 2001 From: "Gustavo A. R. Silva" Date: Mon, 26 Sep 2022 18:03:41 -0500 Subject: iwlegacy: 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.
