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.
