From c79cd9a24ef71c5d9b9185a20b387391abaa6cc7 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Thu, 18 Oct 2018 15:10:15 +0200 Subject: [PATCH] scsi: dpt_i2o: use dma_set_mask The driver currently uses pci_set_dma_mask despite otherwise using the generic DMA API. Also move the dma_get_required_mask check before actually setting the dma mask, so that we don't end up with inconsistent settings in corner cases.
