It's fix released for systemd, not for linux.

The bug reporter thought the wireless hotkey doesn't work because of these  
events showed in dmesg, but in the end it's because udevd's hwdb doesn't  
register the hotkey to emit wlan event.
Nevertheless these messages should be suppressed, otherwise it may still  
confuse users in the future.
