[PATCH 03/15] media: blackfin: bfin_capture: set min_buffers_needed
From: Lad, Prabhakar
Date: Sat Dec 20 2014 - 05:48:24 EST
this patch sets the min_buffers_needed field of the vb2 queue
so that the vb2 core will make sure start_streaming() callback
is called only when we have minimum buffers queued.
