My reading from the commit 415606588c61 ("PTP: introduce new versions
of IOCTLs") is that we have an issue with the version 1 and hence we
added ver 2 of the existing ops. Since it's a new implementation, I
can skip the old part and just implement ver 2.
However, I can do something like
     #define PTP_SYS_OFFSET_ANY PTP_OFFSET_ANY2
is that something inline with the mix of ver 1 and ver 2 expectation?
