Subject: [PATCH v6 10/28] ufs: core: Only call ufshcd_add_command_trace() for SCSI commands
Date: Tue, 14 Oct 2025 13:15:52 -0700 [thread overview]
Message-ID: <20251014201707.3396650-11-bvanassche@acm.org> (raw)
In-Reply-To: <20251014201707.3396650-1-bvanassche@acm.org>
Instead of checking inside ufshcd_add_command_trace() whether 'cmd' points
at a SCSI command, let the caller perform that check. This patch prepares
for removing the lrbp->cmd pointer.
