Subject: [PATCH] dma-direct: Export dma_direct_alloc() and dma_direct_free()
Date: Tue,  5 Feb 2019 12:06:02 +0100	[thread overview]
Message-ID: <20190205110602.27717-1-thierry.reding@gmail.com> (raw)

From: Thierry Reding <treding@nvidia.com>

Drivers that are built as modules may want to use these functions, so
make them available like the rest of the functions.
