From 9a1cf85c9c7cca15bfc452f207818977621dedf8 Mon Sep 17 00:00:00 2001 From: Kees Cook Date: Mon, 10 Mar 2025 15:23:40 -0700 Subject: [PATCH] wifi: carl9170: Add __nonstring annotations for unterminated strings When a character array without a terminating NUL character has a static initializer, GCC 15's -Wunterminated-string-initialization will only warn if the array lacks the "nonstring" attribute[1]. Mark the arrays with __nonstring to and correctly identify the char array as "not a C string" and thereby eliminate the warning.
