If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 5fb2da104f842ebe9807d91eaba0893b50d16c67 Author: Yang Yingliang <yangyingliang@xxxxxxxxxx> Date: Fri Dec 2 01:38:50 2022 -0800 mcb: mcb-parse: fix error handing in chameleon_parse_gdd() [ Upstream commit 728ac3389296caf68638628c987aeae6c8851e2d ] If mcb_device_register() returns error in chameleon_parse_gdd(), the refcount of bus and device name are leaked. Fix this by calling put_device() to give up the reference, so they can be released in mcb_release_dev() and kobject_cleanup().
