Subject: [PATCH 10/28] venus: vdec: call session_continue in insufficient event
Date: Tue, 24 Apr 2018 15:44:18 +0300	[thread overview]
Message-ID: <20180424124436.26955-11-stanimir.varbanov@linaro.org> (raw)
In-Reply-To: <20180424124436.26955-1-stanimir.varbanov@linaro.org>

Call session_continue for Venus 4xx version even when the event
says that the buffer resources are not sufficient. Leaving a
comment with more information about the workaround.
