We are using Nemo boards with 64-bit dual-core PWRficient PA6T-1682M CPUs (A-EON AmigaOne X1000). [1] The RC2 of kernel 5.15 works without any problems on our Nemo boards. [2] Could you please post all your patches merged in one patch? It's easier for me to apply one patch.

I think the address could just get removed here, as this is clearly not helpful. port number, which is somewhat useful for identifying the device, now it's either the pointless string, or the virtual address that the device is mapped to, which is not helpful either and potentially leaks information about kernel internal structures.

Yeah, now that I'm looking at it again it doesn't make much sense to include it there. Maybe just dev_name(smbus->dev) instead of the address?
