Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input 

Pull input subsystem updates from Dmitry Torokhov:
 "Thanks to Samuel Thibault input device (keyboard) LEDs are no longer
  hardwired within the input core but use LED subsystem and so allow use
  of different triggers; Hans de Goede did a large update for the ALPS
  touchpad driver; we have new TI drv2665 haptics driver and DA9063
  OnKey driver, and host of other drivers got various fixes"

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input: (55 commits)
  Input: pixcir_i2c_ts - fix receive error
  MAINTAINERS: remove non existent input mt git tree
  Input: improve usage of gpiod API
  tty/vt/keyboard: define LED triggers for VT keyboard lock states
  tty/vt/keyboard: define LED triggers for VT LED states
  Input: export LEDs as class devices in sysfs
  Input: cyttsp4 - use swap() in cyttsp4_get_touch()
  Input: goodix - do not explicitly set evbits in input device
  Input: goodix - export id and version read from device
  Input: goodix - fix variable length array warning
  Input: goodix - fix alignment issues
  Input: add OnKey driver for DA9063 MFD part
  Input: elan_i2c - add product IDs FW names
  Input: elan_i2c - add support for multi IC type and iap format
  Input: focaltech - report finger width to userspace
  tty: remove platform_sysrq_reset_seq

LED handling under Linux
========================
If you're reading this and thinking about keyboard leds, these are
handled by the input subsystem and the led class is *not* needed.
In its simplest form, the LED class just allows control of LEDs from
userspace. LEDs appear in /sys/class/leds/. The maximum brightness of the
LED is defined in max_brightness file. The brightness file will set the brightness
