   4 Subject: [PATCH 170/454] lan78xx: Avoid spurious kevent 4 "error"
   5
   6 lan78xx_defer_event generates an error message whenever the work item
   7 is already scheduled. lan78xx_open defers three events -
   8 EVENT_STAT_UPDATE, EVENT_DEV_OPEN and EVENT_LINK_RESET. Being aware
   9 of the likelihood (or certainty) of an error message, the DEV_OPEN
  10 event is added to the set of pending events directly, relying on
  11 the subsequent deferral of the EVENT_LINK_RESET call to schedule the
  12 work.  Take the same precaution with EVENT_STAT_UPDATE to avoid a
  13 totally unnecessary error message.
