From c326de562f1fc149da4855a1b9d0433300c2a85d Mon Sep 17 00:00:00 2001 From: Hannes Reinecke Date: Mon, 18 Feb 2019 08:34:22 +0100 Subject: [PATCH] scsi: aic94xx: fix calls to dma_set_mask_and_coherent() The change to use dma_set_mask_and_coherent() incorrectly made a second call with the 32 bit DMA mask value when the call with the 64 bit DMA mask value succeeded.
