stable inclusion from stable-v5.10.94 commit 256302cb2f860c07ca7aead179fbd102631848b7 bugzilla: https://gitee.com/openeuler/kernel/issues/I531X9
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
commit ced4913efb0acc844ed65cc01d091a85d83a2082 upstream.
In case device registration fails during probe, the driver state and the embedded platform device structure needs to be freed using platform_device_put() to properly free all resources (e.g. the device name).
