Merge branch 'octeontx2-ptp-bugs'
Subbaraya Sundeep says:
====================
octeontx2: Fix PTP bugs
This patchset addresses two problems found when using
ptp.
Patch 1 - Increases the refcount of ptp device before use
which was missing and it lead to refcount increment after use
bug when module is loaded and unloaded couple of times.
Patch 2 - PTP resources allocated by VF are not being freed
during VF teardown. This patch fixes that.
