Title:
  Dell 7140 avarage power consumption in idle increased by 1.3-1.5 times
  due to events by INT3432

Status in Linux:
  Incomplete
Status in linux package in Ubuntu:
  New

Bug description:
  On Dell Venue 11 Pro 7140 average power consumption in idle increased
  by 1.3-1.5 times due to events coming from INT343A. According to
  powertop since Linux 4.10 INT3432:00 generate around two hundred
  events on average, in /sys/devices/pci0000:00/INT3432:00/i2c-6 there
  is two devices: INT343A and SMO91D0. AFAIK INT343A is rt286.

  With Linux 4.9.0-4.9.45, Linux 4.11.0-4.11.12 in idle there is around 100 
wakeups per second in sum, battery discharge rate around 3-3.5 Watts per second.
  But with Linux 4.9.46-4.9.51, Linux 4.10.0-4.10.17, Linux 4.12.0rc1-4.13.3 - 
around 300 wakeups per second on average, due to events coming from INT3432:00. 
With Linux 4.13.3 battery discharge rate around 4.5 Watts per second.
  Probably some commit was backported to Linux 4.9 between .45 and .46 releases.
  I have no idea why issue is not reproducible on any Linux 4.11 release I 
tried.

  Sometimes INT3432 events rate fall from two hundred to one hundred for
  shorts period of time (for example I observe this right now on Linux
  4.10.0 while removing/installing packages).

  Message like this sometimes appear in dmesg:
  [  731.226730] i2c_hid i2c-SMO91D0:00: i2c_hid_get_input: incomplete report 
(53/13568)

  Complete dmesg with Linux 4.13.3 is attached.
