Subject: [PATCH]aic7xxx: Take the LED out of diagnostic mode on PM resume, too.
Date: Fri, 03 Oct 2008 23:45:29 +0200 [thread overview]
Message-ID: <48E69279.2000507@gmail.com> (raw)

Take the Diag/Activity-LED of the HBA out of diagnostic mode on PM resume after successful PM resume from standby and HBA restart,
it remained always on before. If something fails before complete recovery, it should remain on, since it is a diagnostics LED,
reason for the used higher layer for the clear.
