Comment 18 for bug 1672619

Quick workaround here would be to add an xorg.conf snippet to ignore the mute serial device. Unless you're rebuilding kernels a lot and expect the i2c driver to fail frequently, this won't be a problem otherwise.

For the RMI4 patches, the latest revisions won't make the serial kernel device show up. I'm not 100% sure if that will apply for the i2c patches too. Benjamin? If so, then I think the xorg.conf.d snippet is a good enough workaround until the kernel is in place.
