From 49b56ad0f2523c9fabc59d881c63db355db1e755 Mon Sep 17 00:00:00 2001 From: Miaoqian Lin Date: Thu, 29 Dec 2022 11:25:33 +0400 Subject: [PATCH] platform/x86/amd: Fix refcount leak in amd_pmc_probe [ Upstream commit 6b1c00f9605744686e94981f9c16cf328f88ab86 ] pci_get_domain_bus_and_slot() takes reference, the caller should release the reference by calling pci_dev_put() after use. Call pci_dev_put() in the error path to fix this.
