Subject: ptp: update adjfreq callback description
From: Jacob Keller <[email protected]>
commit 87f4d7c1d36f44b0822053b7e5dedc31fdd0ab99 upstream.
This patch updates the adjfreq callback description to include a note that the
delta in ppb is always relative to the base frequency, and not to the current
frequency of the hardware clock.
