UCSI failing due to probe() getting version 0

[Oliver Neukum <oneukum@xxxxxxxx>]

Hi,

I am trying this on a new laptop, but I am getting a result I do not
understand.
ucsi_acpi_probe() is called, but ucsi_register() fails with -ENODEV,
because ucsi->version is 0.

If I dump the ucsi_acpi buffer I get:

00 00 00 00 02 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00

And, frankly I do not understand that. Why have the ACPI device
but show version number 0?

    Regards
        Oliver
