Subject: [PATCH v1 1/2] scsi: ufs: Simplify completion timestamp for SCSI and query commands
Date: Mon, 6 Jul 2020 14:07:06 +0800 [thread overview]
Message-ID: <20200706060707.32608-2-stanley.chu@mediatek.com> (raw)
In-Reply-To: <20200706060707.32608-1-stanley.chu@mediatek.com>
Simplify recording command completion time in
__ufshcd_transfer_req_compl() by assigning lrbp->compl_time_stamp
in an unified location.
