Pull input fixes from Dmitry Torokhov:

 - a tweak to the IBM Trackpoint driver that helps recognizing
   trackpoints on never Lenovo Carbons

 - a fix to the ALPS driver solving scroll issues on some Dells

 - yet another ACPI ID has been added to Elan I2C toucpad driver

 - quieted diagnostic message in soc_button_array driver

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input:
  Input: ALPS - fix two-finger scroll breakage in right side on ALPS touchpad
  Input: soc_button_array - silence -ENOENT error on Dell XPS13 9365
  Input: trackpoint - add new trackpoint firmware ID
  Input: elan_i2c - add ELAN0602 ACPI ID to support Lenovo Yoga310
