If anyone has any objections, please let me know. ------------------ From: Christophe JAILLET commit be627abcc0d5dbd5882873bd85fbc18aa3d189ed upstream. In the commit in Fixes:, when the code has been updated to use an explicit for loop, instead of for_each_available_child_of_node(), the assumption that a reference to a device_node structure would be released at each iteration has been broken. Now, an explicit of_node_put() is needed to release the reference.
