From: Len Brown Date: Wed, 8 Jul 2009 03:22:58 +0000 (-0400) Subject: ACPI: check acpi_disabled in acpi_table_parse() and acpi_table_parse_entries() X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=e5b8fc6ac158f65598f58dba2c0d52ba3b412f52;p=deliverable%2Flinux.git 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.
