Subject: [PATCH 3.11 035/233] Revert "ACPI: Add BayTrail SoC GPIO and LPSS ACPI IDs"

3.11.10.4 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: "Rafael J. Wysocki" <rafael.j.wysocki@...el.com>

commit 2b844ba79f4a114bd228ad6fee040ffd99a0963d upstream.

This reverts commit f6308b36c411 (ACPI: Add BayTrail SoC GPIO and LPSS
ACPI IDs), because it causes the Alan Cox' ASUS T100TA to "crash and
burn" during boot if the Baytrail pinctrl driver is compiled in.

Fixes: f6308b36c411 (ACPI: Add BayTrail SoC GPIO and LPSS ACPI IDs)
