Subject: [PATCH 2/4] venus: helpers: Add a new helper for buffer processing
Date: Fri, 23 Oct 2020 15:57:02 +0300	[thread overview]
Message-ID: <20201023125704.4984-3-stanimir.varbanov@linaro.org> (raw)
In-Reply-To: <20201023125704.4984-1-stanimir.varbanov@linaro.org>

The new helper will be used from encoder and decoder drivers
to enqueue buffers for processing by firmware.
