From 1f4fe89c9c78d3163cf1e389bdc6438a44b64244 Mon Sep 17 00:00:00 2001 From: Jeff Skirvin Date: Fri, 16 Dec 2011 08:21:21 +0000 Subject: [PATCH] [SCSI] libsas: Remove redundant phy state notification calls. In the case of an explicit sas_phy_enable call to disable a phy, the LLDD provides the calls to sas_phy_disconnected and the PHYE_LOSS_OF_SIGNAL event. NOTE: This assumes that the lldd(s) generate the notification, which appears to be the case, but only verfied on isci.
