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: 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
