Subject: [PATCH] nvme-pci: remove useless assignment in nvme_pci_setup_prps
Date: Sat, 16 Jul 2022 19:49:41 +0800 [thread overview]
Message-ID: <1657972181-72398-1-git-send-email-liusong@linux.alibaba.com> (raw)
From: Liu Song <liusong@linux.alibaba.com>
If prp_list is NULL, nvme_unmap_sg will be performed, and the assignment
to first_dma is meaningless, so remove it.
