Subject: [PATCH v9 09/15] vb2: mark codec drivers as unordered
Date:   Fri,  4 May 2018 17:06:06 -0300
Message-Id: <20180504200612.8763-10-ezequiel@collabora.com>
In-Reply-To: <20180504200612.8763-1-ezequiel@collabora.com>
References: <20180504200612.8763-1-ezequiel@collabora.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

From: Gustavo Padovan <gustavo.padovan@collabora.com>

In preparation to have full support to explicit fence we are
marking codec as non-ordered preventively. It is easier and safer from an
uAPI point of view to move from unordered to ordered than the opposite.

v3: set property instead of callback
v2: mark only codec drivers as unordered (Nicolas and Hans)
