QCA6174 hw2.1?

[jhihn at gmx.com]

I went through the archives, and the  wiki but I still wasn't sure... 
I have a shiny new Lenovo z70, kernel 4.0-rc1/3.  Dmesg reports failures for loading  firmware in /lib/firmware/ath10k/QCA6174/hw2.1/... 
So I found the firmware Git repo,  but it seems to be missing hw2.1. I even symlinked 2.1 to  3.0, no dice. 

I don't dual boot and this is a laptop  so I'm looking to get  my WiFi working.  Any pointers are appreciated.  Thanks.
