Subject: [PATCH 3/9] dma-contiguous: remove dev_set_cma_area
Date: Wed, 30 Sep 2020 10:55:42 +0200	[thread overview]
Message-ID: <20200930085548.920261-4-hch@lst.de> (raw)
In-Reply-To: <20200930085548.920261-1-hch@lst.de>

dev_set_cma_area contains a trivial assignment.  It has just three
callers that all have a non-NULL device and depend on CONFIG_DMA_CMA,
so remove the wrapper.
