hammer LED backlight brightness is not getting set when USB
device is in suspend state.

This patch fixes the issue by requesting USB HID device to be
in FULLON mode, so that sending hardware output report and
hardware raw request won't fail to set brightness, and set
device back to NORMAL mode once this call returns.

The Razer Blade Stealth detects palms too aggressively and this creates
a dead zone around the touchpad. Users like being able to use their
entire touchpad, so we should probably not filter out the "palm" events
from the device and report them as regular touches, leaving the palm
detection up to the upper stack

Sony's NSG-MR5U and NSG-MR7U remote controls have a full keyboard and a
touchpad.  The keyboard is already supported by the existing Linux
kernel and drivers but the touchpad is not recognized.  This patch adds
the coded needed to bring full functionality to the touchpad.

Note that these remotes use the vendor code for SMK even though they are
Sony branded.

Known limitations
- The built-in accelerometers are not supported by these changes
- When the Drag (Fn) key is used as a mouse button, the button is
automatically released when the key begins repeating.  There are two
  workarounds for this 1) Use the button behind the touchpad instead of
  the Drag (Fn) key or 2) Disable the key repeat functionality or
  increase the key repeat delay.

This patch changes all references to ELECOM trackballs using their
series name to refer to them by their model name.

ELECOM provides multiple series of mice such as EX-G, HUGE, and DEFT.
Although it has not caused conflicts in the driver, there can be more
than one iteration of mice in each series. For example, there are 7
variants of EX-G trackballs but only three (M-XT3URBK, M-XT3DRBK, and
M-XT4DRBK) need a driver to work correctly.

There are also 4 DEFT series trackballs but two of them have the same
VID:PID as the other two. I picked the earlier model for the naming of
the PID macros.

Pull GPIO updates from Linus Walleij:
 "The is the bulk of GPIO changes for the v4.16 kernel cycle. It is
  pretty calm this time around I think. I even got time to get to things
  like starting to clean up header includes.

  Core changes:

   - Disallow open drain and open source flags to be set simultaneously.
     This doesn't make electrical sense, and would the hardware actually
     respond to this setting, the result would be short circuit.

   - ACPI GPIO has a new core infrastructure for handling quirks. The
     quirks are there to deal with broken ACPI tables centrally instead
     of pushing the work to individual drivers. In the world of BIOS
     writers, the ACPI tables are perfect. Until they find a mistake in
     it. When such a mistake is found, we can patch it with a quirk. It
     should never happen, the problem is that it happens. So we
     accomodate for it.

   - Several documentation updates.

   - Revert the patch setting up initial direction state from reading
     the device. This was causing bad things for drivers that can't read
     status on all its pins. It is only affecting debugfs information
     quality.

   - Label descriptors with the device name if no explicit label is
     passed in.

   - Pave the ground for transitioning SPI and regulators to use GPIO
     descriptors by implementing some quirks in the device tree GPIO
     parsing code.

  New drivers:

   - New driver for the Access PCIe IDIO 24 family.

  Other:

   - Major refactorings and improvements to the GPIO mockup driver used
     for test and verification.

   - Moved the AXP209 driver over to pin control since it gained a pin
     control back-end. These patches will appear (with the same hashes)
     in the pin control pull request as well.

   - Convert the onewire GPIO driver w1-gpio to use descriptors. This is
     merged here since the W1 maintainers send very few pull requests
     and he ACKed it.

   - Start to clean up driver headers using <linux/gpio.h> to just use
     <linux/gpio/driver.h> as appropriate"
