Subject: [PATCH v1 3/3] drm/msm: Update the MMU helper function APIs
Date: Fri, 22 May 2020 16:03:16 -0600
Message-ID: <20200522220316.23772-4-jcrouse@codeaurora.org> (raw)
In-Reply-To: <20200522220316.23772-1-jcrouse@codeaurora.org>

Instead of using a bare unsigned type for the length value for map/unmap
functions pass in a size_t to more correctly match up with the underlying
APIs.
