This is a note to let you know that I've just added the patch titled gpio: sifive: Fix refcount leak in sifive_gpio_probe to the 5.15-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: gpio-sifive-fix-refcount-leak-in-sifive_gpio_probe.patch and it can be found in the queue-5.15 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 5a3e595e47414d19a5c1166ffd952a3600c2c7b0 Author: Miaoqian Lin <linmq006@xxxxxxxxx> Date: Mon Jan 2 12:20:39 2023 +0400 gpio: sifive: Fix refcount leak in sifive_gpio_probe [ Upstream commit 694175cd8a1643cde3acb45c9294bca44a8e08e9 ] of_irq_find_parent() returns a node pointer with refcount incremented, We should use of_node_put() on it when not needed anymore. Add missing of_node_put() to avoid refcount leak.
