Date: Fri, 14 Aug 2009 16:38:07 -0400 From: Len Brown <lenb@...nel.org> To: x86@...nel.org, sfi-devel@...plefirmware.org, linux-kernel@...r.kernel.org, linux-acpi@...r.kernel.org Cc: Len Brown <len.brown@...el.com>, Feng Tang <feng.tang@...el.com> Subject: [PATCH 03/11] ACPI: check acpi_disabled in acpi_table_parse() and acpi_table_parse_entries() From: Len Brown <len.brown@...el.com> 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.
