> Commit 823eb2a3c4c7 ("PTP: add support for one-shot output") introduced
> a new flag for the PTP periodic output request ioctl. This flag is not
> currently supported by any driver.
> 
> Fix all drivers which implement the periodic output request ioctl to
> explicitly reject any request with flags they do not understand. This
> ensures that the driver does not accidentally misinterpret the
> PTP_PEROUT_ONE_SHOT flag, or any new flag introduced in the future.
> 
> This is important for forward compatibility: if a new flag is
> introduced, the driver should reject requests to enable the flag until
> the driver has actually been modified to support the flag in question.
