Subject: HID: quirks: Fix keyboard + touchpad on Toshiba Click Mini not working
From: Hans de Goede <[email protected]>
commit edfc3722cfef4217c7fe92b272cbe0288ba1ff57 upstream.
The Toshiba Click Mini uses an i2c attached keyboard/touchpad combo (single i2c_hid device for both) which has a vid:pid of 04F3:0401, which is also used by a bunch of Elan touchpads which are handled by the drivers/input/mouse/elan_i2c driver, but that driver deals with pure touchpads and does not work for a combo device such as the one on the Toshiba Click Mini.
The combo on the Mini has an ACPI id of ELAN0800, which is not claimed by the elan_i2c driver, so check for that and if it is found do not ignore the device. This fixes the keyboard/touchpad combo on the Mini not working (although with the touchpad in mouse emulation mode).
