* Input: ALPS - fix touchpad detection when buttons are pressedAkio Idehara2012-02-241-1/+2
| | | | | | | | | | | | | ALPS touchpad detection fails if some buttons of ALPS are pressed. The reason is that the "E6" query response byte is different from what is expected. This was tested on a Toshiba Portege R500.
