From 7583221f6066978487f14caf31b4ea5d99713bfa Mon Sep 17 00:00:00 2001 From: thomas schorpp Date: Fri, 3 Oct 2008 23:45:29 +0200 Subject: [PATCH] [SCSI] aic7xxx: Take the LED out of diagnostic mode on PM resume 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.
