From 6fc5d84e6d85dcb3af6ba32c45fc65304946f134 Mon Sep 17 00:00:00 2001 From: "Gustavo A. R. Silva" Date: Mon, 29 Aug 2022 16:50:59 -0500 Subject: [PATCH] can: etas_es58x: 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 array declaration in union es58x_urb_cmd with the new DECLARE_FLEX_ARRAY() helper macro. This helper allows for a flexible-array member in a union.
