[PATCH 4.8 74/92] ACPI / APEI: Fix incorrect return value of ghes_proc()

From: Greg Kroah-Hartman
Date: Thu Nov 17 2016 - 05:53:21 EST


4.8-stable review patch. If anyone has any objections, please let me know.

------------------

From: Punit Agrawal <punit.agrawal@xxxxxxx>

commit 806487a8fc8f385af75ed261e9ab658fc845e633 upstream.

Although ghes_proc() tests for errors while reading the error status,
it always return success (0). Fix this by propagating the return
value.
