+Subject: [PATCH] Fix build with 64 bits time_t
+
+time element is deprecated on new input_event structure in kernel's
+input.h [1]
+
+This will avoid the following build failure:
+
+hw/input/virtio-input-host.c: In function 'virtio_input_host_handle_status':
+hw/input/virtio-input-host.c:198:28: error: 'struct input_event' has no member named 'time'
+  198 |     if (gettimeofday(&evdev.time, NULL)) {
+      |                            ^
