New Revision: 323421
URL: https://svnweb.freebsd.org/changeset/base/323421

Log:
  MFC r320743:
  
  Fix drivers that assume ticks starts at zero. These drivers all have logic
  similar to "if (ticks > localvar+interval) {localvar=ticks; ...}" where
  localvar is initialized to zero.  Ticks is initialized to a negative value
  since r278230, and that leads to these if statements never being true.
