Need mutex or spinlock to protest against concurrent access.

Ok, thank you. Is it better to add mutex or spinlock in the public place, like ptp_clock_adjtime()?
Then there's no need to add mutex or spinlock in all the drives.

No, that is a terrible idea.  The class layer has no idea about the
hardware implementation.  Only the driver knows that.
