CVE-2025-21924 : In the Linux kernel, during ptp initialization for the hns3 driver, hclge_ptp_get_cycle may fail and previously not unregister/free the clock. The fix calls hclge_ptp_destroy_clock to unregister and free the clock when hclge_ptp_get_cycle fails, mitigating potential resource leaks.
