Merge branch 'for_linus' of git://cavan.codon.org.uk/platform-drivers-x86

Pull x86 platform driver updates from Matthew Garrett:
 "Nothing overly exciting here - a couple of new drivers that don't do a
  great deal, along with some miscellaneous fixes and a couple of small
  feature enablement patches"

* 'for_linus' of git://cavan.codon.org.uk/platform-drivers-x86:
  x86 platform drivers: fix gpio leak
  toshiba_acpi: Add dependency on SERIO_I8042
  asus-nb-wmi: set wapf=4 for ASUSTeK COMPUTER INC. 1015E/U
  Add trivial driver to disable Intel Smart Connect
  Add support driver for Intel Rapid Start Technology
  hp-wmi: add supports for POST code error
  asus-wmi: control wlan-led only if wapf == 4
  drivers/platform/x86/intel_ips: Convert to module_pci_driver
  asus-nb-wmi: ignore ALS notification key code
  asus-wmi: append newline to messages
  x86: asus-laptop: fix invalid point access
  x86: msi-laptop: fix memleak
  amilo-rfkill: Add dependency on SERIO_I8042

What: /sys/bus/acpi/intel-rapid-start/wakeup_events
Date: July 2, 2013
KernelVersion: 3.11
Contact: Matthew Garrett <mjg59@srcf.ucam.org>
Description: An integer representing a set of wakeup events as follows:
1: Wake to enter hibernation when the wakeup timer expires
2: Wake to enter hibernation when the battery reaches a
critical level
These values are ORed together. For example, a value of 3
indicates that the system will wake to enter hibernation when
either the wakeup timer expires or the battery reaches a
critical level.
What: /sys/bus/acpi/intel-rapid-start/wakeup_time
Date: July 2, 2013
KernelVersion: 3.11
Contact: Matthew Garrett <mjg59@srcf.ucam.org>
Description: An integer representing the length of time the system will
remain asleep before waking up to enter hibernation.
This value is in minutes.

config INTEL_RST
tristate "Intel Rapid Start Technology Driver"
depends on ACPI
---help---
This driver provides support for modifying paramaters on systems
equipped with Intel's Rapid Start Technology. When put in an ACPI
sleep state, these devices will wake after either a configured
timeout or when the system battery reaches a critical state,
automatically copying memory contents to disk. On resume, the
firmware will copy the memory contents back to RAM and resume the OS
as usual.
config INTEL_SMARTCONNECT
tristate "Intel Smart Connect disabling driver"
depends on ACPI
---help---
Intel Smart Connect is a technology intended to permit devices to
update state by resuming for a short period of time at regular
intervals. If a user enables this functionality under Windows and
then reboots into Linux, the system may remain configured to resume
on suspend. In the absence of any userspace to support it, the system
will then remain awake until something triggers another suspend.
This driver checks to determine whether the device has Intel Smart
Connect enabled, and if so disables it.
