src bufs belong to out queue, dst bufs belong to in queue. Currently this is not a real problem since all users currently need exactly one input and one output buffer.

A mem-to-mem device is a device that uses memory buffers passed by userspace applications for both their source and destination data. This is different from existing drivers, which utilize memory buffers for either input or output, but not both. In terms of V4L2 such a device would be both of OUTPUT and CAPTURE type. Examples of such devices would be: image 'resizers', 'rotators', 'colorspace converters', etc. This patch adds a separate Kconfig sub-menu for mem-to-mem devices as well.
