Subject: [PATCH 02/11] of: Make of_dma_get_range() private
Date:   Thu, 26 Sep 2019 19:24:46 -0500
Message-Id: <20190927002455.13169-3-robh@kernel.org>

Precedence: bulk

of_dma_get_range() is only used within the DT core code, so remove the
export and move the header declaration to the private header.
