Bug description:
[Impact]
Some RMI4 touchpad doesn't work properly even the probing returns no
error. Further investigation shows the interrupt doesn't increase at
all. There's already a public bug and the patch is already upstreamed:
https://bugs.freedesktop.org/show_bug.cgi?id=91102
[Fix]
There's a fix contains in v4.3-rc1 and has already been tested:
commit 9a98b3387e7bd9af5a6495b32e07d6f25071f4ba
Author: Andrew Duggan <aduggan@xxxxxxxxxxxxx>
AuthorDate: Thu Jul 16 17:14:00 2015 -0700
Commit: Jiri Kosina <jkosina@xxxxxxxx>
CommitDate: Fri Jul 17 11:29:53 2015 +0200
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
