From 1e9dd807c609d1598fa56a1d65074a6eeb89f705 Mon Sep 17 00:00:00 2001 From: "Gustavo A. R. Silva" Date: Mon, 26 Sep 2022 18:01:08 -0500 Subject: soc: qcom: smd-rpm: 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.
