Ignore LED updates for disabled devices

If an XKB AccessX timeout is set and a VT switch is triggered, the
AccessXTimeoutExpire function may be called after the device has already been
disabled. This can cause a null-pointer dereference as our shared libinput
device may have been released by then.

In the legacy drivers this would've simply caused a write to an invalid fd
(-1), not a crash. Here we need to be more careful. Peter Hutterer's avatarPeter Hutterer <>
