This patch fix it.
Furthermore, if the table is not found, return 1 means nothing, and
make it difficult to write the comment. So return -ENOENT when the
table is not found, and correct the comment.
I am OK with the change, but the above description is not very clear.
You should state that all callers only check if the function succeeded
or not. So, you are simplifying the semantics by returning -errno for
all failure cases.
Since you are making this change, I'd suggest you also update the stub
function in linux/acpi.h to return -ENODEV as well.
