* commit '1bd890ad173d79e7906c5e1d06bf0a06cca4519d': hevc: Separate adding residual to prediction from IDCT This commit should be a noop but isn't because of the following renames: - transform_add → add_residual - transform_skip → dequant - idct_4x4_luma → transform_4x4_luma Merged-by: Clément Bœsch <cboesch@gopro.com>
