From ec44a6762fc57c82acdf2c12ec9b542d9f308300 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Thu, 11 Oct 2018 09:56:58 +0200 Subject: scsi: qla4xxx: 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.
