From b1fa122930c4ceeb265f02202c8f42a53a188a88 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Wed, 10 Oct 2018 18:06:50 +0200 Subject: [PATCH] scsi: 3w-sas: fully convert to the generic DMA API The driver is currently using an odd mix of legacy PCI DMA API and generic DMA API calls, switch it over to the generic API entirely.
