From 321c5ade5a06cb561459b5190ed5bd36a270ea5e 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.
