Subject: [PATCH v2 0/2] ptp/ptp_vmw: enhancements to ptp_vmw

This series provides:

- implementation of PTP clock adjustments ops for ptp_vmw driver to
adjust its time and frequency, allowing time transfer from a virtual
machine to the underlying hypervisor.

- add a module parameter probe_hv_port that allows ptp_vmw driver to
be loaded even when ACPI is disabled, by directly probing for the
device using VMware hypervisor port commands.

v2:
- [PATCH 2/2]: remove blank line in ptp_vmw_init()
