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

Browse Source 
Pull input updates from Dmitry Torokhov:

 - the main change is a fix for my brain-dead patch to PS/2 button
   reporting for some protocols that made it in 4.17

 - there is a new driver for Spreadtum vibrator that I intended to send
   during merge window but ended up not sending the 2nd pull request.
   Given that this is a brand new driver we should not see regressions
   here

 - a fixup to Elantech PS/2 driver to avoid decoding errors on Thinkpad
   P52

 - addition of few more ACPI IDs for Silead and Elan drivers

 - RMI4 is switched to using IRQ domain code instead of rolling its own
   implementation

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input:
  Input: psmouse - fix button reporting for basic protocols
  Input: xpad - fix GPD Win 2 controller name
  Input: elan_i2c_smbus - fix more potential stack buffer overflows
  Input: elan_i2c - add ELAN0618 (Lenovo v330 15IKB) ACPI ID
  Input: elantech - fix V4 report decoding for module with middle key
  Input: elantech - enable middle button of touchpads on ThinkPad P52
  Input: do not assign new tracking ID when changing tool type
  Input: make input_report_slot_state() return boolean
  Input: synaptics-rmi4 - fix axis-swap behavior
  Input: synaptics-rmi4 - fix the error return code in rmi_probe_interrupts()
  Input: synaptics-rmi4 - convert irq distribution to irq_domain
  Input: silead - add MSSL0002 ACPI HID
  Input: goldfish_events - fix checkpatch warnings
  Input: add Spreadtrum vibrator driver
