From 569eddcf3a0f4efff4ef96a7012010e0f7daa8b4 Mon Sep 17 00:00:00 2001 From: Xiang Chen Date: Fri, 25 Jan 2019 22:22:30 +0800 Subject: [PATCH] scsi: hisi_sas: send primitive NOTIFY to SSP situation only Send primitive NOTIFY to SSP situation only, or it causes underflow issue when sending IO. Also rename hisi_sas_hw.sl_notify() to hisi_sas_hw. sl_notify_ssp(). Signed-off-by: Xiang Chen Signed-off-by: John Garry Signed-off-by: Martin K.
