Subject: [PATCH] driver core: Display error codes when class suspend fails
Date: Wed, 20 Oct 2010 11:22:42 -0700 [thread overview]
Message-ID: <1287598962-28013-1-git-send-email-broonie@opensource.wolfsonmicro.com> (raw)
Aid diagnostics by printing the error code from failed suspends, which
doesn't otherwise seem to get displayed.
