Subject: [PATCH] dma-buf: A collection of typo and documentation fixes
From:   "T.J. Mercier" <tjmercier@google.com>
To:     Sumit Semwal <sumit.semwal@linaro.org>,
        "=?UTF-8?q?Christian=20K=C3=B6nig?=" <christian.koenig@amd.com>
Cc:     "T.J. Mercier" <tjmercier@google.com>, linux-media@vger.kernel.org,
        dri-devel@lists.freedesktop.org, linaro-mm-sig@lists.linaro.org,
        linux-kernel@vger.kernel.org

Precedence: bulk

I've been collecting these typo fixes for a while and it feels like
time to send them in.
