Hi Johannes,

Thanks for the clarification.
I checked the patchwork build checks, and the failure is indeed caused by the IW61x SDIO IDs
not being defined.

Right, understood. The IW61x SDIO IDs currently appear only in linux-next, not in wireless-next,
and the patchwork build logs confirm the build failure is exactly due to these IDs being
undefined.

For v11, I’ll add a small temporary patch with local fallback #defines (guarded with #ifndef) so
that wireless-next can build independently without relying on any cross-tree merges. I’ll drop
that patch once the IDs reach mainline.

Thanks,
Jeff
