From 30081d8ea47d521e8804398b25f59b8e49a2ed0b Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Wed, 20 Jan 2016 15:01:59 -0800 Subject: [PATCH] sparc: use generic dma_set_mask Sparc already uses the same code as the generic code for the PCI implementation but just fails the call sbus. This moves to the generic implemenation which eventually return -EIO due to the NULL dma_mask pointer in the device. Signed-off-by: Christoph Hellwig Cc: "David S.
