HID: rmi: Set F01 interrupt enable register when not set
Note:
So far the platform we encounter with this issue use GPIO interrupt, so it also needs 3.19.0-32 or Wily kernel to work too.
[Test]
1. Boot with v4.3-rc1 -> pass
2. Boot with patched Vivid kernel -> pass
3. Boot with patched Wily kernel -> pass
