From f29c2f57cdf7a57223dcd9fbaa2261faab5234b2 Mon Sep 17 00:00:00 2001 From: Yang Yingliang Date: Mon, 28 Nov 2022 14:55:12 +0800 Subject: [PATCH] EDAC/i10nm: fix refcount leak in pci_get_dev_wrapper() [ Upstream commit 9c8921555907f4d723f01ed2d859b66f2d14f08e ] As the comment of pci_get_domain_bus_and_slot() says, it returns a PCI device with refcount incremented, so it doesn't need to call an extra pci_dev_get() in pci_get_dev_wrapper(), and the PCI device needs to be put in the error path.
