From f8a571b2a128a1697624c1b132f3af07848ebbcf Mon Sep 17 00:00:00 2001 From: tangchen Date: Mon, 6 Jan 2014 16:47:59 +0800 Subject: ACPI / tables: Return proper error codes from acpi_table_parse() and fix comment. The comment about return value of acpi_table_parse() is incorrect. This patch fix it. Since all callers only check if the function succeeded or not, this patch simplifies the semantics by returning -errno for all failure cases. This will also simply the comment. As suggested by Toshi Kani , also change the stub in linux/acpi.h to return -ENODEV. Signed-off-by: Tang Chen Signed-off-by: Rafael J.
