In part2: 

- A small patch for the RX51 OMAP board (Nokia N900 phone), the patch
   creates a battery monitor device instance, so that it can be probed. It
   was acked by the OMAP maintainer;
 
 - A couple of late bug fixes for the charger-manager: corrects corner
   cases for the battery full handling.

Merge tag 'for-v3.8-part2' of git://git.infradead.org/battery-2.6

Pull battery update, part 2, from Anton Vorontsov:
 "These are left overs that I didn't have time to review/apply before
  the merge window opened.  I didn't want to "spoil" the first pull
  request with these late patches, so they were not included:

   - A small patch for the RX51 OMAP board (Nokia N900 phone), the patch
     creates a battery monitor device instance, so that it can be
     probed.  It was acked by the OMAP maintainer;

   - A couple of late bug fixes for the charger-manager: corrects corner
     cases for the battery full handling."

* tag 'for-v3.8-part2' of git://git.infradead.org/battery-2.6:
  charger-manager: Fix bug when check dropped voltage after fullbatt event
  charger-manager: Fix bug related to checking fully charged state of battery
  ARM: OMAP: rx51: Register platform device for rx51_battery
