Subject: [PATCH V3] acpi: apei: check for pending errors when probing GHES entries
Date: Thu, 18 May 2017 15:22:42 -0600	[thread overview]
Message-ID: <1495142562-7318-1-git-send-email-tbaicar@codeaurora.org> (raw)

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
