[PATCH V3] acpi: apei: check for pending errors when probing GHES entries

From: Tyler Baicar
Date: Thu May 18 2017 - 17:23:01 EST

Check for pending errors when probing GHES entries. It is possible
that a fatal error is already pending at this point, so we should
handle it as soon as the driver is probed. This also avoids a
potential issue if there was an interrupt that was already
cleared for an error since the GHES driver wasn't present.

V3: Check for pending errors of all GHES types
