Subject: [PATCH 2/2] dma-debug: remove all exports
Date: Tue,  8 Sep 2020 18:39:59 +0200	[thread overview]
Message-ID: <20200908163959.3177173-3-hch@lst.de> (raw)
In-Reply-To: <20200908163959.3177173-1-hch@lst.de>

Now that the main dma mapping entry points are out of line none
of these functions can be called from modular code.
