From 246ea3c0ad02386ddfc1ea3031510da8cc86c892 Mon Sep 17 00:00:00 2001 From: Luo Jiaxing Date: Thu, 11 Apr 2019 20:46:43 +0800 Subject: [PATCH] scsi: hisi_sas: Don't fail IT nexus reset for Open Reject timeout Currently we call hisi_sas_softreset_ata_disk() in hisi_sas_I_T_nexus_reset(). If this fails for open reject reason, there is no reason to fail the IT nexus reset, so only fail for TMF_RESP_FUNC_FAILED. Some other strings spilled over multiple lines are reunited.
