Subject[PATCH v4 1/2] media: staging/imx: fill vb2_v4l2_buffer field entry
Date
- fixes gstreamer v4l2src warning:

0:00:00.716640334 349 0x164f720 WARN v4l2bufferpool gstv4l2bufferpool.c:1195:gst_v4l2_buffer_pool_dqbuf:<v4l2src0:pool:src> Driver should never set v4l2_buffer.field to ANY

- fixes v4l2-compliance test failure:

Streaming ioctls:
test read/write: OK (Not Supported)
Video Capture:
Buffer: 0 Sequence: 0 Field: Any Timestamp: 58.383658s
fail: v4l2-test-buffers.cpp(297): g_field() == V4L2_FIELD_ANY

Signed-off-by: Peter Seiderer <ps.report@gmx.net>
---
Changes in v4:
- new patch (put first because patch is needed to advance with
the v4l2-compliance test), thanks to Philipp Zabel
<p.zabel@pengutronix.de> for suggested solution for the right
field value source
