[PATCH 0/3] platform/x86: dell-ddv: Rework battery temperature handling

[Armin Wolf <W_Armin@gmx.de>]

This patch series reworks the handling of the battery temperature
inside the dell-wmi-ddv driver.

The first patch fixes an issue inside the calculation formula for
the temperature value that resulted in strange temperature values
like 29.1 degrees celcius.

The second patch then simplifies the battery hook handling by using
devm_battery_hook_register().

The third patch finally makes use of the new power supply extension
mechanism to expose the battery temperature to userspace. The
power supply extension mechanism also takes care that the temperature
shows up inside the hwmon interface of the associated battery.

All patches where tested on a Dell Inspiron 3505 and appear to work.

  platform/x86: dell-ddv: Fix temperature calculation
  platform/x86: dell-ddv: Use devm_battery_hook_register
