From e5b8fc6ac158f65598f58dba2c0d52ba3b412f52 Mon Sep 17 00:00:00 2001 From: Len Brown <len.brown@intel.com> Date: Tue, 7 Jul 2009 23:22:58 -0400 Subject: [PATCH] ACPI: check acpi_disabled in acpi_table_parse() and acpi_table_parse_entries() Allow consumers of the acpi_table_parse()/acpi_table_parse_entries() API to gracefully handle the acpi_disabled=1 case via return value rather than checking the global flag themselves.
