From 6cc739087784160eff296c7fbd7a95b209f44ba5 Mon Sep 17 00:00:00 2001 From: John Garry Date: Mon, 20 Dec 2021 19:21:25 +0800 Subject: [PATCH] scsi: Revert "scsi: hisi_sas: Filter out new PHY up events during suspend" This reverts commit b14a37e011d829404c29a5ae17849d7efb034893. In that commit, we had to filter out phy-up events during suspend, as it work cause a deadlock between processing the phyup event and the resume HA function try to drain the HA event workqueue to complete the resume process. Now that we no longer try to drain the HA event queue during the HA resume processor, the deadlock would not occur, so remove the special handling for it.
