This text needs to be updated: this isn't a driver, this is the dvb_vb2 core framework. In any case, the patch itself is correct.

This driver uses min_buffers_needed which vb2 uses to ensure start_streaming is called when at least 'min_buffers_needed' buffers are queued. However, this driver doesn't need this, it can stream fine without any buffers queued. Just drop this unnecessary restriction.
