[PATCH] leds: ledtrig-timer trigger_data allocation fix

[Shuah Khan]

ledtrig-timer doesn't allocate memory for trigger_data and assigns
(void *)1 to save state. Fixed it to allocate int instead. Please 
note that non-null trigger_data is used to key off of to do proper
cleanup in deactivation routine and not used during the life of the
trigger itself.
