Please read the code: * ptp_clock_register() - register a PTP hardware clock driver * * @info: Structure describing the new clock. * @parent: Pointer to the parent device of the new clock. * * Returns a valid pointer on success or PTR_ERR on failure. If PHC * support is missing at the configuration level, this function * returns NULL, and drivers are expected to gracefully handle that * case separately. You must handle the NULL pointer case.
