From 2bb3a2bf9939f3361e25045f4ef7b136b864c3b8 Mon Sep 17 00:00:00 2001 From: Aaron Lu Date: Tue, 19 Nov 2013 15:43:52 +0800 Subject: ACPI / fan: use acpi_device_xxx_power instead of acpi_bus equivelant When we have the acpi_device pointer, there is no need to pass the device's handle to the acpi_bus_xxx_power functions to get/set/update the device's power state, instead, use the acpi_device_xxx_power functions directly. To make this happen for fan module, export acpi_device_update_power.
