[Bug 2084191] Re: [X1E] Request: Add support for Lenovo Yoga Slim 7x

@Tobias

It will take me a bit to get back to you on the comparison data as I
will need to go get the concept image again and do all the setup steps I
did to get things working (eg. sound, firmware).  I might even need to
work my way back as you guys are really good about updating the kernel
version on the concept images and my last test was probably back in
January.  I will do the work to get the data, but will probably not get
to it until mid week.
