From 6ebb5bc9e61be4315202c15a0f53f636e8f0bf2e Mon Sep 17 00:00:00 2001 From: Zhang Rui Date: Tue, 3 Sep 2013 08:32:09 +0800 Subject: acpi_processor: convert acpi_evaluate_object() to acpi_evaluate_integer() acpi_evaluate_integer() is an ACPI API introduced to evaluate an ACPI control method that is known to have an integer 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/acpi/acpi_processor.c in this patch.
