From e4cc99efbeb922bbe4b73ef77ce3aa4f76fe1ad2 Mon Sep 17 00:00:00 2001 From: Qiushi Wu Date: Wed, 27 May 2020 16:17:17 -0500 Subject: [PATCH] ACPI: sysfs: Fix reference count leak in acpi_sysfs_add_hotplug_profile() commit 6e6c25283dff866308c87b49434c7dbad4774cc0 upstream. kobject_init_and_add() takes reference even when it fails. Thus, when kobject_init_and_add() returns an error, kobject_put() must be called to properly clean up the kobject.
