From b1cf7a5615157e958c2bdac9aa981676c07a10d9 Mon Sep 17 00:00:00 2001 From: "Gustavo A. R. Silva" Date: Mon, 15 May 2023 13:22:48 -0600 Subject: [PATCH] mlxfw: 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 alone in structs with the new DECLARE_FLEX_ARRAY() helper macro. This helper allows for flexible-array members alone in structs.
