From 54d47689c6e3892ddb24004e07bfcb3f23aa0222 Mon Sep 17 00:00:00 2001 From: Kees Cook Date: Tue, 3 Jan 2023 15:48:36 -0800 Subject: [PATCH] drm/nouveau/fb/ga102: Replace zero-length array of trailing structs with flex-array Zero-length arrays are deprecated[1] and are being replaced with flexible array members in support of the ongoing efforts to tighten the FORTIFY_SOURCE routines on memcpy(), correctly instrument array indexing with UBSAN_BOUNDS, and to globally enable -fstrict-flex-arrays=3. Replace zero-length array with flexible-array member. This results in no differences in binary output.
