From: John Garry Date: Tue, 26 Jan 2016 17:31:17 +0000 (+0800) Subject: hisi_sas: fix v1 hw check for slot error X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=0f28ede906a8ad44158a6ef9471a5a412343cced;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git hisi_sas: fix v1 hw check for slot error Completion header bit CMPLT_HDR_RSPNS_XFRD flags whether the response frame is received into host memory, and not whether the response frame has an error. As such, change the decision on whether a slot has an error. Also redundant check on CMPLT_HDR_CMD_CMPLT_MSK is removed.
