[PATCH v2 05/36] media: qcom: venus: Remove useless setting of min_buffers_needed

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
