X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=91978465b1e5f89025cd43cd2102943160ec6dee;p=linux-beck.git

[SCSI] zfcp: Reorder registration of initial SCSI device

Make sure that the rport registration did complete and then register
SCSI device directly. Otherwise the unit_enqueue would race with the
call to zfcp_scsi_queue_unit_register.
