From d844752e1801099f92c178845f56412861a2b4af Mon Sep 17 00:00:00 2001 From: Raghava Aditya Renukunta <RaghavaAditya.Renukunta@microsemi.com> Date: Thu, 16 Feb 2017 12:51:23 -0800 Subject: [PATCH] scsi: aacraid: Fix a potential spinlock double unlock bug The driver does not unlock the reply queue spin lock after handling SMART adapter events. Instead it might attempt to unlock an already unlocked spin lock. Fixed by making sure the driver locks the spin lock before freeing it. Thank you dan for finding this issue out.
