[PATCH 0/2 REPOST] remove unneded irq save

[Sebastian Andrzej Siewior <bigeasy@xxxxxxxxxxxxx>]

This is the repost of the two patches I posted in earlier this month:

- [PATCH 1/2] libsas: remove irq save in sas_ata_qc_issue()
  Received feedback but nothing really changed. I explained that this is
  not about "local_irqsave() + spin_lock()" *but* "local_irq_save() +
  spin_unlock()". This seemed to have been overseen twice.
  Also there were two opinions about the TODO comment:
     /* TODO: audit callers to ensure they are ready for qc_issue to
      * unconditionally re-enable interrupts
   It is unclear to me if this comment should be removed because it
   makes no sense or if the intention was indeed to audit callers code
   for a possible "spin_unlock_irq(ap->lock);".

- [PATCH 2/2] qla2xxx: remove irq save in qla2x00_poll()
  Received no feedback.
