Subject: [PATCH 2/4] dma-iommu: replace device arguments
Date: Wed, 7 Jul 2021 16:55:03 +0900 [thread overview]
Message-ID: <20210707075505.2896824-3-stevensd@google.com> (raw)
In-Reply-To: <20210707075505.2896824-1-stevensd@google.com>
From: David Stevens <stevensd@chromium.org>
Replace the struct device argument with the device's nid in
__iommu_dma_alloc_pages, since it doesn't need the whole struct. This
allows it to be called from places which don't have access to the
device.
