+Subject: [PATCH] Suppress new gcc-15 -Wunterminated-string-initialization
+
+GCC 15 now warns when character arrays are being initialized by strings
+and terminating NUL character doesn't fit. GCC 15.1 also allows marking
+such arrays with nonstring attribute to suppress the warning. W/o such
+attribute, the warning becomes error due to the global -Werror. Add the
+attribute accordingly.
+
+Fixes these errors:
+
