linux-toradex.git/drivers/edac/edac_device_sysfs.c, branch v5.14 Linux kernel for Apalis and Colibri modules EDAC: Fix reference count leaks 2020-06-17T13:38:35+00:00 Qiushi Wu wu000273@umn.edu 2020-05-28T20:22:37+00:00 17ed808ad243192fb923e4e653c1338d3ba06207 When kobject_init_and_add() returns an error, it should be handled because kobject_init_and_add() takes a reference even when it fails. If this function returns an error, kobject_put() must be called to properly clean up the memory associated with the object. Therefore, replace calling kfree() and call kobject_put() and add a missing kobject_put() in the edac_device_register_sysfs_main_kobj() error path.
