ktime_set(S,N) was required for the timespec storage type and is still
useful for situations where a Seconds and Nanoseconds part of a time value
needs to be converted. For anything where the Seconds argument is 0, this
is pointless and can be replaced with a simple assignment.

This was entirely automated, using the script by Al:

to do the replacement at the end of the merge window.

Pull more x86 platform driver updates from Darren Hart:
 "Move and add registration for the mlx-platform driver. Introduce
  button and lid drivers for the surface3 (different from the
  surface3-pro). Add BXT PMIC TMU support. Add Y700 to existing
  ideapad-laptop quirk.

  Summary:

  ideapad-laptop:
   - Add Y700 15-ACZ to no_hw_rfkill DMI list

  surface3_button:
   - Introduce button support for the Surface 3

  surface3-wmi:
   - Add custom surface3 platform device for controlling LID
   - Balance locking on error path

  mlx-platform:
   - Add mlxcpld-hotplug driver registration
   - Fix semicolon.cocci warnings
   - Move module from arch/x86

  platform/x86:
   - Add Whiskey Cove PMIC TMU support"

Like other Y700 models Lenovo Y700 15-ACZ does not have a physical rfkill switch.
ideapad-laptop wrongly reports all radios as blocked by hardware which causes
wireless network connections to fail.

Add this model without an rfkill switch to the no_hw_rfkill list.

The Surface 3 is not following the ACPI spec for PNP0C40, but nearly.
The device is connected to a I2C device that might have some magic
but we don't know about.
Just create the device after the enumeration and use the declared GPIOs
to provide button support.

This driver is just an adaptation of drivers/input/misc/soc_button_array.c

The Surface Pro 3 is using an ACPI driver and matches against the bid
of the device ("VGBI"). To prevent this incompatible driver to be used
on the Surface Pro, we add a match on the Surface 3 bid "TEV2".

The LID state provided by ACPI on the Surface 3 is not accurate.
The ACPI node doesn't get notified on LID open, which means the
LID input switch stays close most of the time.

Fortunatelly, there is a WMI method which directly queries the
GPIO underneath the LID state, so it's far more reliable than ACPI.
To get the notifications that the LID was opened/closed, we can
rely on the ACPI notification of the touchscreen: the DSDT shows
that the touchscreen will get notified on close/open as it also
controls its _STA method.

Note that we need to set the tag "power-switch" to the LID
input node through a udev rule for logind to accept it:

SUBSYSTEM=="input", KERNEL=="event*", KERNELS=="surface3-wmi", \
	TAG+="power-switch"

Add calls for mlxcpld-hotplug platform driver registration/unregistration
and add platform hotplug data configurations. This driver, when registered
within system will handle system hot-plug events for the power suppliers,
power cables and fans (insertion and removing). These events are
controlled through CPLD Lattice device.
