What is the purpose of capture_fourcc? It is not used.

capture_type is not used in the patch. Does fb_sz take effect in later patches? _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
