From: Christoph Hellwig Date: Thu, 18 Oct 2018 13:10:21 +0000 (+0200) Subject: scsi: lpfc: use dma_set_mask_and_coherent X-Git-Tag: Ubuntu-5.0.0-8.9~923^2~196 X-Git-Url: https://git.proxmox.com/?a=commitdiff_plain;h=f30e1bfd61541edfd6fa1622013978e6f9c47564;p=mirror_ubuntu-disco-kernel.git scsi: lpfc: use dma_set_mask_and_coherent The driver currently uses pci_set_dma_mask despite otherwise using the generic DMA API. Switch it over to the better generic DMA API. Signed-off-by: Christoph Hellwig Signed-off-by: Martin K.
