From b75596ceedf9709edb8192adc1d8ede1407a67ac Mon Sep 17 00:00:00 2001 From: Suganath Prabu S Date: Thu, 17 Nov 2016 16:15:58 +0530 Subject: [PATCH] scsi: mpt3sas: Unblock device after controller reset Orabug: 25639713 While issuing any ATA passthrough command to firmware the driver will block the device. But it will unblock the device only if the I/O completes through the ISR path. If a controller reset occurs before command completion the device will remain in blocked state. Make sure we unblock the device following a controller reset if an ATA passthrough command was queued.
