RE: [PATCH 2/2] HID: hid-multitouch: Add Flatfrog support

Hi all,

A small note of appreciation: 
We at Flatfrog appreciate the work done by all the people involved in the Linux touch/input development. It is wonderful to see that even if we lack resources to commit a driver patch this can still be done by experts (and enthusiast) elsewhere.

Thank you so much,
Flatfrog's software team

I sent the wrong version, the one below is the correct one. Sorry about
the fuzz.
