Hi, Vojtech!
Recent kernels allow exclusive usage of input device when
input device is grabed. keyboard_tasklet does not check
device state and switch LED's of all keyboards. However
grabed device may be use another LED steering code.
This patch forbid keyboard_tasklet switch LED's of
grabed devices.
