stable inclusion from stable-v5.10.89 commit 7a37f2e370699e2feca3dca6c8178c71ceee7e8a bugzilla: 186140 https://gitee.com/openeuler/kernel/issues/I4S8HA
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
commit 26a8b09437804fabfb1db080d676b96c0de68e7c upstream.
In case device registration fails during module initialisation, the platform device structure needs to be freed using platform_device_put() to properly free all resources (e.g. the device name).
