motorola-montana: touchscreen doesn't work

Here's full dmesg: http://paste.ubuntu.com/p/BprJFhdxpD/ If we leave only important parts, we get this:

I already installed firmware for touchscreen, so I'm left with only two ideas:

1. You need to change firmware path in kernel
2. Something else in kernel is wrong
