CVE-2025-21814

In the Linux kernel, the following vulnerability has been resolved:

ptp: Ensure info->enable callback is always set

The ioctl and sysfs handlers unconditionally call the ->enable callback.
Not all drivers implement that callback, leading to NULL dereferences.
Example of affected drivers: ptp_s390.c, ptp_vclock.c and ptp_mock.c.

Instead use a dummy callback if no better was specified by the driver.
