Subject: [PATCH net 0/8] ibmvnic: Fix a race in ibmvnic_probe()

If we get a transport (reset) event right after a successful CRQ_INIT
during ibmvnic_probe() but before we set the adapter state to VNIC_PROBED,
we will throw away the reset assuming that the adapter is still in the
probing state. But since the adapter has completed the CRQ_INIT any
subsequent CRQs the we send will be ignored by the vnicserver until
we release/init the CRQ again. This can leave the adapter unconfigured.

While here fix a couple of other bugs that were observed (Patches 1,2,4).

Sukadev Bhattiprolu (8):
  ibmvnic: free reset-work-item when flushing
  ibmvnic: initialize rc before completing wait
  ibmvnic: define flush_reset_queue helper
  ibmvnic: complete init_done on transport events
  ibmvnic: register netdev after init of adapter
  ibmvnic: init init_done_rc earlier
  ibmvnic: clear fop when retrying probe
  ibmvnic: Allow queueing resets during probe
