From: Dmitry Torokhov dmitry.torokhov@gmail.com
[ Upstream commit a4c2a13129f7c5bcf81704c06851601593303fd5 ]
TUXEDO BU1406 does not implement active multiplexing mode properly, and takes around 550 ms in i8042_set_mux_mode(). Given that the device does not have external AUX port, there is no downside in disabling the MUX mode.
