Subject: [PATCH v2 12/20] scsi: ufs: Rework ufshcd_change_queue_depth()
Date: Fri, 19 Nov 2021 11:57:35 -0800 [thread overview]
Message-ID: <20211119195743.2817-13-bvanassche@acm.org> (raw)
In-Reply-To: <20211119195743.2817-1-bvanassche@acm.org>
Prepare for making sdev->host->can_queue less than hba->nutrs. This patch
does not change any functionality.
