Description

In the Linux kernel, the following vulnerability has been resolved: rapidio: fix possible name leaks when rio_add_device() fails Patch series "rapidio: fix three possible memory leaks". This patchset fixes three name leaks in error handling. - patch #1 fixes two name leaks while rio_add_device() fails. - patch #2 fixes a name leak while rio_register_mport() fails. This patch (of 2): If rio_add_device() returns error, the name allocated by dev_set_name() need be freed. It should use put_device() to give up the reference in the error path, so that the name can be freed in kobject_cleanup(), and the 'rdev' can be freed in rio_release_dev().
