Subject: [PATCH 02/20] lpfc: Fix premature re-enabling of interrupts in lpfc_sli_host_down
Date:   Sat, 21 Sep 2019 20:58:48 -0700

Sender: linux-scsi-owner@vger.kernel.org
Precedence: bulk

Use of spin_lock_irq may re-enable interrupts prematurely.

Convert to spin_lock. Note: code is under the phba->hba_lock which
has been locked with irqsave.
