Chengen Du 6bd12be3fa udev: Handle PTP device symlink properly on udev action 'change'
PTP device symlink creation rules are currently executed only when the
udev action is 'add'. If a user reloads the rules and runs the udevadm
trigger command to reapply changes, the symlink may be deleted, which
can prevent the chronyd service from restarting properly.
