coda: support of decoding

[Gaëtan Carlier]

Hello,
I see in code source of coda driver that decoding is not supported.

ctx->inst_type = CODA_INST_DECODER;
v4l2_err(v4l2_dev, "decoding not supported.\n");
return -EINVAL;

Is there any technical reason or the code has not been written ?

Thanks a lot,
Best regards,
Gaëtan Carlier.
