From cfb72c08912f794e442b2561c808dd0e5c8abd85 Mon Sep 17 00:00:00 2001 From: "Gustavo A. R. Silva" Date: Wed, 16 Feb 2022 13:49:15 -0600 Subject: [PATCH] ath: Replace zero-length arrays with flexible-array members MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit There is a regular need in the kernel to provide a way to declare having a dynamically sized set of trailing elements in a structure. Kernel code should always use “flexible array members”[1] for these cases. The older style of one-element or zero-length arrays should no longer be used[2].
