From 4aac26ecb4ace3df840af95408f2279c85684f62 Mon Sep 17 00:00:00 2001 From: kehuanlin Date: Wed, 6 Sep 2017 17:58:39 +0800 Subject: scsi: ufs: fix wrong command type of UTRD for UFSHCI v2.1 commit 83dc7e3dea76b77b6bcc289eb86c5b5c145e8dff upstream. Since the command type of UTRD in UFS 2.1 specification is the same with UFS 2.0. And it assumes the future UFS specification will follow the same definition.
