Series vb2/cedrus: use timestamps to identify buffers | expand

Commit Message

Hans Verkuil Dec. 12, 2018, 12:39 p.m. UTC 
From: Hans Verkuil <hverkuil-cisco@xs4all.nl>

Use the new v4l2_m2m_buf_copy_data helper function and use
timestamps to refer to reference frames instead of using
buffer indices.
