+Subject: [PATCH 60/69] DSS2: Avoid div by zero when calculating required fclk
+MIME-Version: 1.0
+Content-Type: text/plain; charset=utf-8
+Content-Transfer-Encoding: 8bit
+
+When calculating the required fclk rate for five tap filtering if the
+display width and output width are equal div by zero could occur. The
+TRM doesn't actually specify how this case should be handled but for
+now just skip the calculation which would trigger the div by zero.
