From 57e06e0e2a862bd40df47c7ad752fcad1d04c259 Mon Sep 17 00:00:00 2001 From: Daniel Mack Date: Wed, 23 May 2018 11:14:26 +0300 Subject: wcn36xx: set DMA mask explicitly The device takes 32-bit addresses only, so inform the DMA API about it. This is the default on msm8016, so that doesn't change anything, but it's best practice to be explicit.
