From 74ebe3e733b791f37415b3a1b917ee5035bc7364 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Wed, 13 Feb 2019 08:01:02 +0100 Subject: [PATCH] net: pasemi: set a 64-bit DMA mask on the DMA device The pasemi driver never set a DMA mask, and given that the powerpc DMA mapping routines never check it this worked ok so far. But the generic dma-direct code which I plan to switch on for powerpc checks the DMA mask and fails unsupported mapping requests, so we need to make sure the proper 64-bit mask is set.
