While this will fix the issue, I think this is not technically
correct (i.e. micropatching SPI controller via I2C pram struct,
even though the structs appear to be identical).

As the spi_param is needed outside of the SPI driver, we'd
better re-introduce the struct, I think.

I'll send some fixes for this and other issues in this file.

Thanks,
