From 3c0b60618118745220bc0f9bf27e51e37367427c Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Fri, 28 Sep 2012 06:24:18 -0300 Subject: [PATCH] [media] videobuf2-core: fill in length field for multiplanar buffers length should be set to num_planes in __fill_v4l2_buffer(). That way the caller knows how many planes there are in the buffer.
