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 <toshi.kani@hp.com>, also change the stub in linux/acpi.h to return -ENODEV. Signed-off-by: Tang Chen <tangchen@cn.fujitsu.com> Signed-off-by: Rafael J.
