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