    SubjectINPUT: keyboard_tasklet - don't touch LED's of already grabed device
    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.
