should return negative error code instead of a positive value count.

I have two comments on the patch itself:
1) Whenever you have a fix for the code, you need to annotate it using the
"Fixes: tag". See file Documentation/process/submitting-patches.rst in your
source tree.
2) The version change stuff should be in the following order:
Signed-off-by: ....

v2 - fixed compile error

Body of patch.
Placing it where you did would cause the details of "making the sausage" be
saved in the commit log. The reviewer and maintainer need to see it, but not the
end user.
