Subject: [PATCH 04/17] drm/nouveau/gk20a: stop setting DMA_ATTR_NON_CONSISTENT
Date: Mon, 14 Sep 2020 16:44:20 +0200 [thread overview]
Message-ID: <20200914144433.1622958-5-hch@lst.de> (raw)
In-Reply-To: <20200914144433.1622958-1-hch@lst.de>
DMA_ATTR_NON_CONSISTENT is a no-op except on PARISC and some mips
configs, so don't set it in this ARM specific driver part.
