So, this line fails:
  https://elixir.bootlin.com/linux/v5.19-rc4/source/drivers/spi/spi.c#L2399
Can you double check that is true in your case?

If so, it mean that by some reason we can't find registered SPI controller.

You may add a debug print before this
https://elixir.bootlin.com/linux/v5.19-rc4/source/drivers/spi/spi.c#L4224

  dev_info(dev, "%s <--> %s\n", acpi_dev_name(ACPI_COMPANION(dev->parent)),
acpi_dev_name(data));

Meanwhile can you attach file from `acpidump -o ux3402za.dat` or if there is
known publicly available dump (GitHub?) share that link?

P.S. Regarding booting v5.19-rc5, possible this thread will shed a light
