Subject: [PATCH] sony-laptop: Ignore missing _DIS method on pic device
Date: Thu, 16 Oct 2008 17:29:10 -0400 [thread overview]
Message-ID: <1224192550-366-1-git-send-email-ajax@redhat.com> (raw)
From: Matthew Garrett <mjg59@srcf.ucam.org>
At least the Vaio VGN-Z540N doesn't have this method, so let's not fail
to suspend just because it doesn't exist.
