Actually in Android the system will try to invoke the early_suspend during a phone call. but it can not go to the deep sleep because of the wakelock. so I suggest that the psensor driver should be added the wakelock to prevent the issue.
Please add and check the follows:

Title:
  Device trying to suspend when screen is turned off by proximity sensor

Bug description:
  phablet@ubuntu-phablet:~$ system-image-cli -i
  current build number: 202
  device name: krillin
  channel: ubuntu-touch/utopic-proposed
  last update: 2014-08-21 03:59:43
  version version: 202
  version ubuntu: 20140821
  version device: 20140811.1

  Device tries to suspend when the screen is turned off by the proximity
  sensor (when a voicecall is in place).

  Looking at powerd, there's no active suspend blocker when the
  proximity sensor disables the screen, forcing powerd to go in suspend
  state.

  The device shouldn't try to suspend when a voicecall is active (or
  when the proximity sensor is the one turning the screen off).

  When the call starts:
  powerd-cli: Running as user is not fully supported.
  System State Requests:
    Name: com.canonical.Unity.Screen, Owner: :1.18, State: 1

  After putting my hand on top of the device (to trigger the proximity sensor):
  phablet@ubuntu-phablet:~$ powerd-cli list
  powerd-cli: Running as user is not fully supported.
  System State Requests:
    None
