stable inclusion from stable-5.10.51 commit 048624ad564cb2b52ad4552a7e87942acefe0b3e bugzilla: 175263 https://gitee.com/openeuler/kernel/issues/I4DT6F

--------------------------------
commit 51dd19a7e9f8fbbb7cd92b8a357091911eae7f78 upstream.
If the symlink is unable to be created, the driver goes ahead and continues device creation. Instead lets propagate the failure, and fail the probe.
