From 2a3ca1429589521df49fd9348fc382c34b57a88f Mon Sep 17 00:00:00 2001 From: Zhang Rui Date: Tue, 3 Sep 2013 08:31:59 +0800 Subject: [PATCH] i915: intel_acpi: convert acpi_get_handle() to acpi_has_method() acpi_has_method() is a new ACPI API introduced to check the existence of an ACPI control method. It can be used to replace acpi_get_handle() in the case that 1. the calling function doesn't need the ACPI handle of the control method. and 2. the calling function doesn't care the reason why the method is unavailable. Convert acpi_get_handle() to acpi_has_method() in drivers/gpu/drm/i915/intel_acpi.c in this patch. Signed-off-by: Zhang Rui Acked-by: Daniel Vetter Signed-off-by: Rafael J.
