Subject: [PATCH 02/10] nouveau: reset dma_nr in nouveau_dmem_migrate_alloc_and_copy
Date: Wed, 14 Aug 2019 09:59:20 +0200 [thread overview]
Message-ID: <20190814075928.23766-3-hch@lst.de> (raw)
In-Reply-To: <20190814075928.23766-1-hch@lst.de>
When we start a new batch of dma_map operations we need to reset dma_nr,
as we start filling a newly allocated array.
