tee: optee: fix possible memory leak in optee_register_device()
stable inclusion from stable-v5.10.157 commit b547bf71fa7e35e22dd6494588a71ebd318aae09 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I7MU59 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=b547bf71fa7e35e22dd6494588a71ebd318aae09 -------------------------------- [ Upstream commit cce616e0 ] If device_register() returns error in optee_register_device(), the name allocated by dev_set_name() need be freed. As comment of device_register() says, it should use put_device() to give up the reference in the error path. So fix this by calling put_device(), then the name can be freed in kobject_cleanup(), and optee_device is freed in optee_release_device().
