This is a note to let you know that I've just added the patch titled memory: ti-aemif: Drop child node when jumping out loop to the 4.19-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: memory-ti-aemif-drop-child-node-when-jumping-out-loo.patch and it can be found in the queue-4.19 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit d4fddf0fe2618e92a238c2545488de5f438853b3 Author: Pan Bian <bianpan2016@xxxxxxx> Date: Thu Jan 21 01:03:59 2021 -0800 memory: ti-aemif: Drop child node when jumping out loop [ Upstream commit 94e9dd43cf327366388c8f146bccdc6322c0d999 ] Call of_node_put() to decrement the reference count of the child node child_np when jumping out of the loop body of for_each_available_child_of_node(), which is a macro that increments and decrements the reference count of child node. If the loop is broken, the reference of the child node should be dropped manually.
