From 77c39851401121046b3129de9e5aeb2fd5ef7405 Mon Sep 17 00:00:00 2001 From: Zhang Rui Date: Tue, 3 Sep 2013 08:31:54 +0800 Subject: intel-smartconnect: convert acpi_evaluate_object() to acpi_execute_simple_method() acpi_execute_simple_method() is a new ACPI API introduced to invoke an ACPI control method that has single integer parameter and no return value.

This API can simplify the code because the calling function does not need to use the specified acpi_buffer structure required by acpi_evaluate_object(); Convert acpi_evaluate_object() to acpi_evaluate_integer() in drivers/platform/x86/intel-smartconnect.c in this patch.
