Merge tag 'for-v4.1' of git://git.infradead.org/battery-2.6
Pull power supply and reset changes from Sebastian Reichel: - new API for safe access of power supply function attrs - devres support for power supply (un)registration - new drivers / chips: - generic syscon based poweroff driver - iio & charger driver for da9150 - fuel gauge driver for axp288 - bq27x00: add support for bq27510 - bq2415x: add support for bq24157s - twl4030-madc-battery: convert to iio consumer - misc fixes * tag 'for-v4.1' of git://git.infradead.org/battery-2.6: (66 commits) power: twl4030_madc_battery: Add missing MODULE_ALIAS power: twl4030-madc-battery: Convert to iio consumer. dt: power: Add docs for generic SYSCON poweroff driver. power: reset: Add generic SYSCON register mapped poweroff. power: max17042_battery: add missed blank power: max17042_battery: Use reg type instead of chip type power/reset: at91: big endian fixes for atsama5d3x power_supply: charger-manager: Fix dereferencing of ERR_PTR HID: input: Fix NULL pointer dereference when power_supply_register fails power: constify of_device_id array power/reset/rmobile-reset.c: Fix !HAS_IOMEM build power_supply: 88pm860x_charger: Fix possible NULL pointer dereference and use of initialized variable arm: mach-pxa: Decrement the power supply's device reference counter mfd: ab8500: Decrement the power supply's device reference counter power_supply: bq2415x_charger: Decrement the power supply's device reference counter power_supply: 88pm860x_charger: Decrement the power supply's device reference counter x86/olpc/xo15/sci: Use newly added power_supply_put API x86/olpc/xo1/sci: Use newly added power_supply_put API power_supply: charger-manager: Decrement the power supply's device reference counter power_supply: Increment power supply use counter when obtaining references ...
