+Subject: [PATCH] virt: Drop ATTRIBUTE_UNUSED for virt_eventloop_timeout_cb
+
+ATTRIBUTE_UNUSED seems to be never was a public part of the libvirt interface
+and leads to the following issue with recent libvirt versions were
+ATTRIBUTE_UNUSED has been renamed to G_GNUC_UNUSED:
+
+src/virt.c:2209:49: error: expected ';', ',' or ')' before 'ATTRIBUTE_UNUSED'
+ 2209 | static void virt_eventloop_timeout_cb(int timer ATTRIBUTE_UNUSED,
+      |                                                 ^~~~~~~~~~~~~~~~
+src/virt.c: In function 'register_event_impl':
+src/virt.c:2222:26: error: 'virt_eventloop_timeout_cb' undeclared (first use in this function)
+ 2222 |                          virt_eventloop_timeout_cb, NULL, NULL) < 0) {
+      |                          ^~~~~~~~~~~~~~~~~~~~~~~~~
+src/virt.c:2222:26: note: each undeclared identifier is reported only once for each function it appears in
+
+Drop ATTRIBUTE_UNUSED here as there is little use from it.
