From c48a29d065cfa18c3e8699f5e3a84a59ad35e062 Mon Sep 17 00:00:00 2001 From: Heiko Carstens Date: Thu, 1 Dec 2005 02:46:32 +0100 Subject: [SCSI] zfcp: fix spinlock initialization Move initialization of locks and lists to adapter allocation function. Otherwise we might end up with some uninitialized locks, like e.g. the erp locks which only will be inititialized if an error recovery thread for an adapter will be started.
