Groan, I even had that locally!
The unpack operation is redundant for 16-bit sensor formats, don't set the hardware to do it in these cases. Signed-off-by: Naushir Patuck <[email protected]>

@njhollinghurst sadly I think this fix is only partially complete. We only remove the REMAP mode for direct CSI-2 output, not the FE output. From reading the spec, if |

Yes, the only workaround when using FE is to use the 'wildcard' DT (which is equivalent to reverting 98b1f0d) with the side-effect that it will then capture metadata and other DTs. FE could in theory crop out the different components, but better to avoid FE altogether if we can. |

Merging this now as it's correct, but fixing the core issue still needs quite a bit of additional work. |
