In the interest of making this a straight back port to 5.10 that does 
not have all of the __free() goodies, I would just add the missing 
of_node_put() where necessary.

Also, since this is a bug fix, you should probably make it appear 
earlier in the patch series, or even sent it as a separate fix entirely.
