| Subject: Input: i8042 - add TUXEDO BU1406 (N24_25BU) to the nomux list |
| |
| commit a4c2a13129f7c5bcf81704c06851601593303fd5 upstream. |
| |
| 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. |
