Yes please. Commit 88263208 introduced five kernel warnings but I think
only one of these should be removed again, e.g. as follows:

diff --git a/drivers/scsi/qla2xxx/qla_isr.c b/drivers/scsi/qla2xxx/qla_isr.c
index cd39ac18c5fd..d81b5ecce24b 100644
--- a/drivers/scsi/qla2xxx/qla_isr.c
+++ b/drivers/scsi/qla2xxx/qla_isr.c
@@ -2780,8 +2780,6 @@ qla2x00_status_entry(scsi_qla_host_t *vha, struct
rsp_que *rsp, void *pkt)

if (rsp->status_srb == NULL)
sp->done(sp, res);
- else
- WARN_ON_ONCE(true);
}
