From 6db51abb8dc3919b85c5d2afd35b3871399e8a81 Mon Sep 17 00:00:00 2001 From: James Smart Date: Wed, 14 Aug 2019 16:56:59 -0700 Subject: [PATCH] scsi: lpfc: Fix upcall to bsg done in non-success cases The scsi transport fc bsg interface does not expect the bsg_job_done() callback to be done if the bsg request call returns failure. Several of the HST_VENDOR cases in the driver unconditionally call bsg_job_done() regardless of the returning value. Fix the code to only call bsg_job_done() if the call to lpfc_bsg_request() will return success. Signed-off-by: Dick Kennedy Signed-off-by: James Smart Signed-off-by: Martin K.
