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

* git://git.infradead.org/battery-2.6:
  git-battery vs git-acpi
  Power supply class and drivers: remove non obligatory return statements
  pda_power: clean up irq, timer
  MAINTAINERS: Add maintainers for power supply subsystem and drivers

Fixed up trivial conflict in drivers/w1/slaves/w1_ds2760.c manually
