[patch 16/27] zfcp: Update dbf calls

[Christof Schmitt <christof.schmitt@de.ibm.com>]

[-- Attachment #1: 717-zfcp-structure-cleanup-2.diff --]
[-- Type: text/plain, Size: 63358 bytes --]

From: Swen Schillig <swen@vnet.ibm.com>

Change the dbf data and functions to use the zfcp_dbf prefix
throughout the code. Also change the calls to dbf to use zfcp_dbf
instead of zfcp_adapter.
