6.11-stable review patch. If anyone has any objections, please let me know. ------------------ From: Dan Carpenter <dan.carpenter@xxxxxxxxxx> [ Upstream commit 6188a1c762eb9bbd444f47696eda77a5eae6207a ] This code accidentally uses && where || was intended. It potentially results in a NULL dereference. Thus, fix the if-statement expression to use the correct condition. Fixes: 86f271f22bbb ("PCI: keystone: Add workaround for Errata #i2037 (AM65x SR 1.0)") Link: https://lore.kernel.org/linux-pci/1b762a93-e1b2-4af3-8c04-c8843905c279@stanley.mountain Signed-off-by: Dan Carpenter <dan.carpenter@xxxxxxxxxx> [kwilczynski: commit log] Signed-off-by: Krzysztof Wilczyński <kwilczynski@xxxxxxxxxx> Reviewed-by: Manivannan Sadhasivam <manivannan.sadhasivam@xxxxxxxxxx> Reviewed-by: Siddharth Vadapalli <s-vadapalli@xxxxxx> Signed-off-by: Sasha Levin <sashal@xxxxxxxxxx> --- drivers/pci/controller/dwc/pci-keystone.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/pci/controller/dwc/pci-keystone.c b/drivers/pci/controller/dwc/pci-keystone.c index 52c6420ae2003..95a471d6a586d 100644 --- a/drivers/pci/controller/dwc/pci-keystone.c +++ b/drivers/pci/controller/dwc/pci-keystone.c @@ -577,7 +577,7 @@ static void ks_pcie_quirk(struct pci_dev *dev) */ if (pci_match_id(am6_pci_devids, bridge)) { bridge_dev = pci_get_host_bridge_device(dev); - if (!bridge_dev && !bridge_dev->parent) + if (!bridge_dev || !bridge_dev->parent) return; ks_pcie = dev_get_drvdata(bridge_dev->parent); -- 2.43.0
