From: Luis Henriques
Date: Mon Dec 15 2014 - 09:37:48 EST


3.16.7-ckt3 -stable review patch. If anyone has any objections, please let me know.

------------------

From: sensoray-dev <linux-dev@xxxxxxxxxxxx>

commit 1f391217ad8d7cd7b1e48e6e2abf49970cd91d18 upstream.

length is the size of the buffer, not the payload. That's set using
vb2_set_plane_payload().
