This is a note to let you know that I've just added the patch titled PCI: tegra: Fix OF node reference leak to the 5.10-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: pci-tegra-fix-of-node-reference-leak.patch and it can be found in the queue-5.10 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit e945f2e8e7f1e75f5598064d4cbd6eecdadfc25d Author: Christophe JAILLET <christophe.jaillet@xxxxxxxxxx> Date: Tue May 4 19:17:42 2021 +0200 PCI: tegra: Fix OF node reference leak [ Upstream commit eff21f5da308265678e7e59821795e606f3e560f ] Commit 9e38e690ace3 ("PCI: tegra: Fix OF node reference leak") has fixed some node reference leaks in this function but missed some of them. In fact, having 'port' referenced in the 'rp' structure is not enough to prevent the leak, until 'rp' is actually added in the 'pcie->ports' list. Add the missing 'goto err_node_put' accordingly.
