Subject: [PATCH 4.14 178/193] media: venus: venc: fix bytesused v4l2_plane field

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

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

From: Stanimir Varbanov <stanimir.varbanov@...aro.org>

commit 5232c37ce244db04fd50d160b92e40d2df46a2e9 upstream.

This fixes wrongly filled bytesused field of v4l2_plane structure
by include data_offset in the plane, Also fill data_offset and
bytesused for capture type of buffers only.
