From: Ben Collins Date: Mon, 12 Jun 2006 22:15:20 +0000 (-0400) Subject: sbp2: fix deregistration of status fifo address space X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=e269d276792684a13ab0d9acd8c024ec7d6c5f4d;p=openwrt%2Fstaging%2Fblogic.git sbp2: fix deregistration of status fifo address space The proper designator of an invalid CSR address is ~(u64)0, not (u64)0. Use the correct value in initialization and deregistration. Also, scsi_id->sbp2_lun does not need to be initialized twice. (scsi_id was kzalloc'd.)
