Same issue. I see Guenter also replied with similar. We need something
more 'known' as an identity.  I see you sent quite a few patches out on
similar issues.  I'd suggest perhaps focusing on just getting one or two
through the process as it will save time on duplicated feedback like this.
You can scale up later!

one other thing inline.

This line has changed suggesting you are working on on old tree.  Give
7.3-rc1 is out, that is a good base for new pathes at this point.

This line should be under the spi_device_id table, so please move it in this
patch as well as adding the acpi one.
