** Description changed: [Impact] As title, after upgrading to latest Vivid kernel the touchscreen failed. After bisecting shows this revert cause the regression: commit 95df597989f6f297db63dd8669656d10f5f48eb1 Author: Andy Shevchenko <andriy.shevche...@linux.intel.com> 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 de16d55206c5ce82ad44590b01718fbe2323853c Author: Andy Shevchenko <andriy.shevche...@linux.intel.com> Date: Fri Dec 4 23:49:19 2015 +0200 ACPI / LPSS: allow to use specific PM domain during ->probe() - For Vivid it's a simple clean pick (plus a one line change for header - file). + For Vivid it depends on a patch to device core for adding + BUS_NOTIFY_DRIVER_NOT_BOUND notification, both are clean cherry-pick. 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. [Test] 3.19.0-56 -> Failed 3.19.0-56 + patches -> OK (Including suspend) 4.4.0-15 -> OK 4.4.0-15 + revert patch -> OK 4.4.0-15 + patches -> N/A
