Subject: [PATCH RFT 0/5] hwmon: Introduce hwmon_update_groups()

Introduce and use hwmon_update_groups() to support changing sysfs
attribute visibility dynamically without having to re-register
affected hardware monitoring devices.

Use the new function in the ACPI power meter driver.

RFT: The new function was tested extensively with a dummy driver
which changes attribute visibility every few seconds. However,
it was not tested in the 'real world'.

----------------------------------------------------------------
Guenter Roeck (5):
      hwmon: Handle attribute visibility evaluation in device core
      hwmon: Provide helper function to find thermal zones
      hwmon: Add support for updating thermal zones
      hwmon: Implement hwmon_update_groups()
      hwmon: (acpi_power_meter) Use hwmon_update_groups() to update sensor visibility
