commit 7978db344719dab1e56d05e6fc04aaaddcde0a5e upstream.
The for_each_available_child_of_node() loop in _of_add_opp_table_v2() doesn't drop the reference to "np" on errors. Fix that.

I don't think you test-built this patch :(
I actually compile tested the 4.9 patch and found the function to be exactly same in 4.4 branch and skipped it being lazy. And the laziness always proves that it was a bad decision to skip compiling it :(
Sorry for the ++ crap (It took me several minutes to see how your committed change is different from what I have sent) :(
