[PATCH V3 3/8] pktcdvd: Consolidate DPRINTK and VPRINTK macros
From: Joe Perches
Date: Mon Jun 03 2013 - 12:46:19 EST
Use the more common pkt_dbg(level, fmt, ...) form.
These messages are emitted at KERN_NOTICE.
Always emit function name with pkt_dbg(2, ...) uses and
remove the sometimes abbreviated embedded function name.
This form always verifies the format and arguments.
