From 413cda95648d705a7cc6c33d2e81bdccf6ea9a59 Mon Sep 17 00:00:00 2001 From: "Gustavo A. R. Silva" Date: Mon, 26 Sep 2022 16:49:04 -0500 Subject: [PATCH] ipw2x00: 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 arrays declarations in anonymous union with the new DECLARE_FLEX_ARRAY() helper macro. This helper allows for flexible-array members in unions.
