Hi all,

occasionally the qedf driver will crash in fc_lookup_rport() due to missing
locking and incorrect reference counting of the fc_rport_priv() structure
from libfc. This patchset fixes up the reference counting and ensures that
the locking rules of libfc are followed.

As usual, comments and reviews are welcome.

Hannes Reinecke (5):
  qedf: fixup bit operations
  qedf: fixup locking in qedf_restart_rport()
  qedf: missing kref_put in qedf_xmit()
  qedf: remove stale variables in qedf_eh_XXX functions
  qedf: fc_rport_priv reference counting fixes
