Search only the pending list and return immediately on the first hit. When the transfer queue was introduced, the function was used to deal with write transfer -> draw -> write transfer sequence. It was used to tell if the second transfer intersects with the first transfer. If yes, the transfer queue avoided reordering the second transfer to before the draw (by flushing) in case the draw uses the transferred data. With the recent changes to the transfer code, the function is used to deal with write transfer -> readback transfer We want to avoid reordering the readback transfer to before the first transfer (also by flushing). In the old code, we needed to track the compeleted transfers as well to avoid reordering. But in the new code, a readback transfer is guaranteed to see the data from the completed transfers (in other words, it cannot be reoderered to before the already completed transfers). We don't need to search the COMPLETED_LIST. Signed-off-by: Chia-I Wu <olvaffe@gmail.com> Reviewed-by: Alexandros Frantzis <alexandros.frantzis@collabora.com>
