Subject: [PATCH] Input: i8042 - add TUXEDO BU1406 (N24_25BU) to the nomux list
Date: Tue, 28 Feb 2017 17:20:57 -0800	[thread overview]
Message-ID: <20170301012057.GA5402@dtor-ws> (raw)

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.
