Merge git://git.infradead.org/battery-2.6

* git://git.infradead.org/battery-2.6:
  apm_power: check I.intval for zero value, we use it as the divisor
  MAINTAINERS: remove kernel-discuss@handhelds.org list
  pda_power: implement polling
  pda_power: various cleanups
  apm_power: support using VOLTAGE_* properties for apm calculations
  pda_power: add suspend/resume support
  power_supply: add few more values and props
  pda_power: only register available psu
  power: fix incorrect unregistration in power_supply_create_attrs error path
  power: remove POWER_SUPPLY_PROP_CAPACITY_LEVEL
  [BATTERY] power_supply_leds: use kasprintf
  [BATTERY] Every file should include the headers containing the prototypes for its global functions.

@ -87,6 +87,10 @@ batteries use voltage for very approximated calculation of capacity.
Battery driver also can use this attribute just to inform userspace
about maximal and minimal voltage thresholds of a given battery.
VOLTAGE_MAX, VOLTAGE_MIN - same as _DESIGN voltage values except that
these ones should be used if hardware could only guess (measure and
retain) the thresholds of a given power supply.
CHARGE_FULL_DESIGN, CHARGE_EMPTY_DESIGN - design charge values, when
battery considered full/empty.

ENERGY_FULL, ENERGY_EMPTY - same as above but for energy.
CAPACITY - capacity in percents.
CAPACITY_LEVEL - capacity level. This corresponds to
POWER_SUPPLY_CAPACITY_LEVEL_*.
TEMP - temperature of the power supply.
TEMP_AMBIENT - ambient temperature.
