====================
net/ibmvnic: serialization fixes

This series includes two fixes. The first improves reset code to allow
linkwatch_event to proceed during reset. The second ensures that no more
than one thread runs in reset at a time.

v2:
- Separate change param reset from do_reset()
- Return IBMVNIC_OPEN_FAILED if __ibmvnic_open fails
- Remove setting wait_for_reset to false from __ibmvnic_reset(), this
  is done in wait_for_reset()
- Move the check for force_reset_recovery from patch 1 to patch 2

v3:
- Restore reset’s successful return in open failure case

v4:
- Change resetting flag access to atomic
