Subject: [PATCH 30/32] acpi: apei: check for pending errors when probing GHES
entries
Git-commit: 77b246b32b2c4bc21e352dcb8b53a8aba81ee5a4
Patch-mainline: v4.13-rc1
References: fate#323583
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.
