Bug Description

Users of Lenovo Thinkpad Yoga 260 laptops can't use the touchscreen if it has been deactivated from Windows beforehand.

d4a9689 HID: wacom: Support switching from vendor-defined device mode on G9 and G11
967143a HID: wacom: Initialize hid_data.inputmode to -1
b107ac0 HID: wacom: break out parsing of device and registering of input

d4a9689 is the actual fix and the two others make this a clean cherry-pick.

[Test Case]
On a Lenovo Thinkpad Yoga 260, try using the touchscreen.

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-xenial' to 'verification-done-xenial'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See for documentation how to enable and use -proposed. Thank you!
