From: James Smart Date: Tue, 3 Sep 2019 21:54:41 +0000 (-0700) Subject: scsi: lpfc: Fix reset recovery paths that are not recovering X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=4fb86a6bc549fc482bdb21086aa272668ed955d2;p=linux.git scsi: lpfc: Fix reset recovery paths that are not recovering A recent patch unconditionally marks the hba as in error as part of resetting the adapter. The driver flow that called the adapter reset was a recovery path, which expects the adapter to not be in an error state in order to finish the recovery. Given the new error state being set, the recovery fails and the adapter is left in limbo. Revise the adapter reset routine so that it will only mark the adapter in error if it was unable to reset the adapter.
