This new code is only relevant for the CSI_SINK_PAD.

Yes. Right above the modification there is a call to csi_try_fmt which
will already fix up sdformat->format for the source pads. So for the
CSI_SRC_PAD_DIRECT and CSI_SRC_PAD_IDMAC this should amount to a no-op.
If might be better to move this into a separate function and only call
it if sdformat->pad == CSI_SINK_PAD.
