+Subject: [PATCH kmscube] Detect gst_bo_map/_unmap and use it (or avoid it)
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Those functions are not available on libMali, thus breaking
+builds and creating havoc.
+
+Removing the specific parts of the code that deal with
+gbm_bo_map() and gbm_bo_unmap() renders the kmscube utility
+a little less useful, but still valuable.

Some implementations of GBM, like the one included with libMali, do not have gbm_bo_map() nor gbm_bo_unmap(). This patch enables kmscube to work with those implementations even if it doesn't work as great.
