+From 754b0ca247b2d789f9f613f8757b9732494e9489 Mon Sep 17 00:00:00 2001

+Subject: [PATCH] Fix build with GCC 15
+
+GCC 15 defaults to C23, in which the interpretation of function
+declarations without parameters changed from unspecified to `void`.  This
+results in `control_handle_lac_status` not being compatible with the
+expected callback function type.  Adding the expected type parameters,
+albeit unused, fixes the compatibility.
+
+Upstream-Status: Submitted [https://github.com/xelerance/xl2tpd/pull/272]
+Signed-off-by: Martin Jansa <martin.jansa@gmail.com>
