[Bug 1603975] [NEW] thinkpad yoga 260 wacom touchscreen not working

 

Public bug reported:

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

[Fix]
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.
