If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit ec399a2ae7dcb1633c3e786bfd89ce6f94060676 Author: Yang Yingliang <yangyingliang@xxxxxxxxxx> Date: Thu Nov 10 16:24:23 2022 +0800 media: solo6x10: fix possible memory leak in solo_sysfs_init() [ Upstream commit 7f5866dd96d95b74e439f6ee17b8abd8195179fb ] If device_register() returns error in solo_sysfs_init(), 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().
