From 2ca2afe760bf1f78ee410749332d85f9413a9f3a Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ky=C3=B6sti=20M=C3=A4lkki?= Date: Tue, 17 Jun 2014 15:41:37 +0300 Subject: ACPI S3 support: Add acpi_s3_resume_allowed() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add this to reduce the amount of preprocessor conditionals used in the source, compiler currently resolves this to a constant. Once we have gone through all #if CONFIG_HAVE_ACPI_RESUME cases, we may change the implementation to enable/disable S3 support runtime.
