Bug Description
[Impact]
As title, after upgrading to latest Vivid kernel the touchscreen failed. After bisecting shows this revert cause the regression:
commit 95df597989f6f29
Author: Andy Shevchenko <email address hidden>
Date: Fri Dec 4 23:49:18 2015 +0200
Revert "ACPI / LPSS: allow to use specific PM domain during ->probe()"
[Fix]
The reverted patch has had a revised version upstreamed:
commit de16d55206c5ce8
Author: Andy Shevchenko <email address hidden>
Date: Fri Dec 4 23:49:19 2015 +0200
ACPI / LPSS: allow to use specific PM domain during ->probe()
For Vivid it depends on a patch to device core for adding BUS_NOTIFY_
For Xenial the touchscreen still works because the original patch is not reverted, and with the patch reverted the I2C touchscreen still works fine, so I'll skip Xenial for this patch.
For Wily it also contains the revert patch as Vivid, but the I2C on X360 still works.
[Test]
3.19.0-56 -> Failed
3.19.0-56 + patches -> OK (Including suspend)
4.2.0-34 (with revert patch already) -> OK
4.4.0-15 -> OK
4.4.0-15 + revert patch -> OK
4.4.0-15 + patches -> N/A
