The function is newly added by commit c3b60ab7a4dff ("ptp: Add
getmaxphase callback to ptp_clock_info"), adding everyone from

The issue is that we introduce a new sysfs node that depends on a
hardware capability not all PTP devices support. On PTP devices that do
not support this capability, this leads to the NULL pointer dereference
since the driver callback for the functionality if not implemented. I
will submit a fix to the net mailing list along with the appropriate
recipients.
