Was this patch created against a tree that has modifications to device tree

locking?
  I get a hang due to deadlock when I apply it.  Patch to verify the
cause is below.

Ummm... I may have forgotten to enable CONFIG_LOCKDEP when testing. Try
the following fix, and can you please pass me that brown paper bag.

Nononono, I need to keep the bag for my own future use :-)

The following fix looks good and boots successfully on the dragonboard.

    dt: Create unlocked version of for_each_child_of_node()
    
    When iterating over nodes, sometimes it needs to be done when the DT
    lock is already held. This patch makes an unlocked version of the
    for_each_child_of_node() macro.
