Modern glibc is very insistent that you care about whether write()
succeeds:
../hw/dmx/input/usb-keyboard.c: In function ‘kbdUSBCtrl’:
../hw/dmx/input/usb-keyboard.c:292:9: warning: ignoring return value of ‘write’, declared with attribute warn_unused_result [-Wunused-result]
write(priv->fd, &event, sizeof(event));
