Subject: [PATCH v2 4/4] scsi: ufs: Use UPIU query trace in devman_upiu_cmd
Date:   Mon, 31 May 2021 12:43:08 +0200

From: Bean Huo <beanhuo@micron.com>

Since devman_upiu_cmd is not COMMAND UPIU, and doesn't have
CDB, it is better to use UPIU query trace, which provides more
helpful information for issue shooting.
