Yes I think it should be possible to have a jpeg helpers library or a common
file for preparing jpeg headers and I am open to look into it but would prefer
to track that as a separate patch and not in this series as I want to spend
some time to design it properly.

For now,  I was thinking if I can move all these byte arrays too to
include/media/jpeg.h and update it in V4 and then as a separate patch series
introduce the jpeg encoder helper module which export API to prepare JPEG helpers.

Kindly let me know your opinion.

It's the size of both chroma and luma qp_tables, maybe I can have a macro
QP_TABLE_SIZE instead of using magic numbers.
