Wysocki" Cc: Zhang Rui , linux-acpi@vger.kernel.org, linux-kernel@vger.kernel.org Subject: [PATCH 3/4] ACPI / fan: use acpi_device_xxx_power instead of acpi_bus equivelant Date: Tue, 3 Dec 2013 16:28:31 +0800 Message-Id: <1386059312-2990-4-git-send-email-aaron.lu@intel.com> X-Mailer: git-send-email 1.8.3.1 In-Reply-To: <1386059312-2990-1-git-send-email-aaron.lu@intel.com> References: <1386059312-2990-1-git-send-email-aaron.lu@intel.com> Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org 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.
