Subject: [PATCH 03/15] media: blackfin: bfin_capture: set min_buffers_needed
Date: Sat, 20 Dec 2014 16:17:30 +0530 [thread overview]
Message-ID: <1419072462-3168-4-git-send-email-prabhakar.csengg@gmail.com> (raw)
In-Reply-To: <1419072462-3168-1-git-send-email-prabhakar.csengg@gmail.com>
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.
