From 0454a3dc87472d62d8ab967d4d28d8c01c85217d Mon Sep 17 00:00:00 2001 From: Dmitry Baryshkov Date: Mon, 25 Jan 2021 02:28:26 +0300 Subject: [PATCH] PCI: Release OF node in pci_scan_device()'s error path [ Upstream commit c99e755a4a4c165cad6effb39faffd0f3377c02d ] In pci_scan_device(), if pci_setup_device() fails for any reason, the code will not release device's of_node by calling pci_release_of_node(). Fix that by calling the release function. Fixes: 98d9f30c820d ("pci/of: Match PCI devices to OF nodes dynamically") Link: https://lore.kernel.org/r/20210124232826.1879-1-dmitry.baryshkov@linaro.org Signed-off-by: Dmitry Baryshkov Signed-off-by: Bjorn Helgaas Reviewed-by: Leon Romanovsky Signed-off-by: Sasha Levin --- drivers/pci/probe.c | 1 + 1 file changed, 1 insertion(+) diff --git a/drivers/pci/probe.c b/drivers/pci/probe.c index 8fa13486f2f1..f28213b62527 100644 --- a/drivers/pci/probe.c +++ b/drivers/pci/probe.c @@ -2299,6 +2299,7 @@ static struct pci_dev *pci_scan_device(struct pci_bus *bus, int devfn) pci_set_of_node(dev); if (pci_setup_device(dev)) { + pci_release_of_node(dev); pci_bus_put(dev->bus); kfree(dev); return NULL;
