Hi, Markus

It is useful indeed. Although I didn't run cocci script, since it can 
produce too many false result which is hard to filter out.

BTW, I see you haver done the work already, I guess I won't send any 
patches related to 'missing put_device after of_find_device_by_node()'. 
Any idea why these pathes didn't get applied ?

Best regards,
Yu Kuai
