Subject: [PATCH 1/2] scsi: ufs: Introduce a vops to get info of command completion
Date:   Mon,  4 Jan 2021 19:15:50 -0800
Message-Id: <1609816552-16442-2-git-send-email-cang@codeaurora.org>
In-Reply-To: <1609816552-16442-1-git-send-email-cang@codeaurora.org>
References: <1609816552-16442-1-git-send-email-cang@codeaurora.org>
Precedence: bulk

Similar with the vops setup_xfer_req in ufshcd_send_command(), this change
adds the vops compl_xfer_req in __ufshcd_transfer_req_compl() such that
vendor drivers can make use of the two hooks to do variant stuffs.
